Rat Hotrod 1 Watt Push-Pull Handwired Valve Guitar Amp Powerscaling Buffered Loop

Bias/Gain/Bright Switches Valve Rectifier Hammond 125B This was a Custom Build by Andy of Rat Electronics - and not a 'modded stock amp'. Entirely Hand Wired - he used only the metal chassis and the cabinet of an Epiphone Valve Junior. Electrically it is beautifully behaved, and it's dead quiet compared to many other valve amps which hiss, hum and crackle. Unlike Andy's usual amps this one runs the entire gamut from low gain to high gain sounds. And it takes pedals beautifully... It's in beautiful condition. Only ever used at home - and I don't play it enough, so it's for sale. Unlike other large scale production low watt amplifiers - this amplifier is ALL VALVE (no cheap diode clipping here) and incorporates Tri-Rectifier with EZ-80 Valve  A Switch on the Rear Panel of the Amp Allows the Selection of 3 Different Rectifiers. 1. Silicon - Standard 'Silicon' Diodes. 2. V1 - 'Valve Rectifier' - Running at Half Power. 3. V2 - 'Valve Rectifier' - Running at Full Power. All Amplifiers use a Rectifier to convert the Raw AC Voltage from the Mains Transformer into DC Voltage. The Amp Circuits Need DC Voltage to work. If, for example, you Hit a Power Chord on your Guitar, the Amplifier Circuitry Suddenly Demands a Large Dose of Power from the Mains Transformer. Silicon Diodes are Extremely Efficient and can convert the Raw AC into DC almost instantaneously, to Feed the Amplifiers Needs. Valve Rectifiers are a Different Story. Generally Speaking, they can't Cope with Sudden High Demands of Energy and they 'Starve' the Amp of Power until they can catch up with the Demand - This is Called 'SAG' - and it Sounds GREAT! The typical sound Produced by an Amp using 'Silicon' Diodes would be - - Attack - Sustain - Release - Decay - Using the 'V1 Valve' Rectifier, the Sound would be Closer to - - Attack - Swell - Extended Sustain - Release - Decay - To your Ears - In 'Silicon Mode' the Initial Note Attack is Sharp and Crisp - Like a Modern Amp. In 'V1 -or- V2 Valve Mode' the Initial Attack is Almost Soft and Laid Back with Longer Sustain - Like a Vintage Amp.Switchable Valve rectification (Silicon, V1 and V2).  so you get those lovely 'sag' sounds 3 Position Bias Switch      1 - NFB (think Fender Princeton)      2 - I'm not sure:-)) - sounds lovely for jazzy clean sounds though      3 - Modern higher gain amps (think Mesa) 3 position Gain Switch (low, medium and high gain) 3 position bright switch (for a little Fender Fullerton Sparkle) There are many Factors that influence the 'Voice' of a Valve Amplifier but the Dominant Voicing is usually achieved by setting the 'Bias' and 'Gain' on the Preamp Valve. This is preset by the Manufacturer, with No User Access. As the end user, You Can change the Volume and Tone of the Amplifier but can not generally access the Primary 'Voice' Settings. The 3 Position 'Bias' Switch and 3 Position 'Gain' Switch together give you 9 Combinations of 'Voice' settings on the Preamp Valve. From 'Pure Clean' -to- 'Major Overdrive'. A full comprehensive tone stack (Drive, Treble, Middle, Bass, Presence and Master Volume) Two 12AX7 preamp valves, switchable between 1 or 2 (use both 12AX7s for higher gain) Power Scaling (Output Power Reduction - OPR1 and OPR2)        OPR-1 (Only the output valves are power-scaled)        OPR-2 (Preamp & output valves are power-scaled) 'OPR' lets you get a true 'Cranked Amp Sound' at VERY Low Volume Levels - Fat Harmonics - Sustain a Mile Long - the Full works, but at a Volume level you can 'Talk' over. Simple to use, Just like a Normal Volume Control, as you 'Dial Down the Power' - The Volume Drops but the Tone is Maintained. 'OPR' Allows the Output Power of the Amplifier to be Varied from 100% down to Less than 1% of the Full Rating - Fully Maintaining the Warm Tone and Natural Harmonics of the Output Valves - Waste Heat from the Output Stage is Dramatically reduced as the Power is Dialled down, Greatly Extending Valve Life - Because of the Extra Filtering used in the Circuit, Background 'Noise' is Eliminated - Power Consumption is also Reduced, this will extend the life of all the Components in the Amplifier. The 'OPR' Circuitry is Extremely Effective and Reliable. Think in terms of a 'Light Dimmer' in the Amplifier, the basic concept is the same. Certain Voltages in a Valve Amplifier must be Maintained while others can be manipulated, directly influencing the Output Power of the Amp. Unlike a Speaker Attenuator (L-Pad or Power Brake) that 'Loads' the Output of the Amp and Stresses everything to the Edge, The 'OPR' System gives the Amps Critical Components (Valves and Output Transformer) a Holiday. When the 'OPR' Control is set to Full Power (not being Used) it has NO Effect on the Amp 'AT ALL'. The Amp will work the Same as if  'OPR' was Never Fitted. At Bedroom Volume you can TRULY obtain the Full, Sweet Valve Harmonic Overdrive Sound that you have probably always been looking for.

Marshall JVM-1 - 1 Watt Head - 50th Anniversary 1 Watt Valve Guitar Amp (JVM1 / JVM 1)

Selling my 50th Anniversary Marshall JVM1H. These were made in limited numbers (only of the JVM1 heads were made), meaning that these are quite rare beasts. There aren’t that many amps on the market which are all-valve 1 watt, 2 channels and also have an FX loop, so this is the perfect “house-friendly” amp without going down the digital route. The all-valve JVM-1H pays tribute to the look and the sound of Marshall’s awesome flagship JVM Series amps, featuring two, foot-switchable channels, three band EQ, a Presence control and a Resonance switch for extra low end. It uses 3 ECC83s and 2 ECC82s to get its awesome tone. On the back panel there’s an Emulated Line Out, FX Loop and Low Power switch which drops down to 0.1 Watt so you can dial in that incredible JVM tone for even lower volume. The clean channel is great, warm - but can be pushed to break-up and the overdrive channel has plenty of saturated gain on tap which can go down to a crunch with the guitar’s volume knob rolled back. The clean and overdrive preamp on the JVM1 is modelled on the clean and OD1 of the JVM410. For full specs and description visit the Marshall website. The amp also comes with a limited edition head cover, power cable, footswitch, manual and certificate of authenticity. It does not come with a speaker cable. The ones Marshall provide are really poor quality. I personally recommend "Designacable" on Amazon. Really good quality cables for about £10. Ad ID: Delivery Service Consumer Credit

Fender Excelsior Pro - Sonic Blue - 13 watt valve guitar amp

Very good condition - a couple of minor nicks and scuffs in the Tolex which hopefully can be seen in the photos. I have upgraded the Tone switch to a Tone pot and added Fender Tiltback legs which make it much easier to hear when playing. It is a really loud 13 watts and takes pedals beautifully. It comes with a Custom Covers padded cover. From the web..... Fender Pawn Shop Excelsior Pro combo amp has to be one of the more distinctively boutiquey guitar amps we've seen. With 13 watts of 6V6 power and a 15" Eminence Weber Legend speaker, the Excelsior Pro sports an unusual E-shaped grille design and a delightfully bizarre crossed-swords front-panel badge. The Excelsior Pro has three inputs - guitar, mic, and accordion - each with individually optimized circuitry. A tremolo circuit (with speed control) and a bright/dark tone switch complete the featureset. If you're in the mood for something different, you've found it - Fender's Pawn Shop Excelsior Pro.

Peavey Valveking Royal 8 all valve 5 Watt guitar amp

Great sounding little amp for practice, recording or small gigs. This amp is in as new condition, with all standard components, except that I've added a built in reverb. The reverb can be switched out from the front panel - in which case the amp circuit is EXACTLY as original - or, when switched in it can be dialled in to give as little or as much effect as needed. I will provide a full circuit diagram of the modification which was designed and installed by a professional (BBC) electronics engineer. I have done one or two small gigs with this amp and used it for recording and practice sessions. It is fairly loud for it's size but don't expect it to keep up with a rock drummer! These amps do sound better through a larger speaker (I tried wiring it up to a 2 x 12" cab and it sounded awesome) but, obviously, a lot of the appeal is its small size and weight. Collection from SE London or I may be able to deliver around London by arrangement. Ad ID: Delivery Service Consumer Credit

Gilmore Jr. 1/2 Watt Tube Guitar Amp

For sale is my great little Gilmore Jr. 1/2 Watt Tube Amp - and 2 watt mod. I used this for a little while with a 1x12 cab trying to keep my volume down whilst still playing a great vintage tube amp sound. I also have the valve and adaptor that take it up to 2 watts - still not that loud but an even cleaner sound. New it would be around £420 plus shipping and import duty AND it would come as a kit - you would have to build it. I barely use it now as I moved to an even smaller amp. For more information search for Gilmore Jr. 1/2 Watt Tube Amp. The kit is made in America by a company called Guytronix. Also - I am sure there are plenty of people discussing its great “articulation at lower volume” and other things that make this such a unique little amp. I might consider trade for a guitar cab.
