Of course you can also put any of your FX pedals at the input of the Preamp, as you normally do with any real guitar amp. (You can't run the speaker-level output of a guitar amp through your Hall Of Fame reverb pedal.) This lets you easily do things like have reverb and delay after the (Preamp) distortion, which are otherwise impossible with a real guitar amplifier except in studio situations. Since the Preamp's output is an instrument-level audio signal, you can run its output into any favourite guitar FX pedals you own. The Flamma Preamp is the most striking example I know of. Digital modelling does it easily, but until just a few years ago, every digital guitar modelling device I heard sounded like garbage, at least until you got well above the $1000 USD price point.īut, at least to my ears, that has changed dramatically in just the last year or two. This is the kind of versatility that you really can't get out of an analogue guitar preamp, whether "toob" or solid-state. Want an instantly recognizable Fender clean tone? Model 1 on the clean setting has what you want. You get 14 different simulations - models of 7 different famous tube guitar amps, each one with a clean and a dirty channel, for a total of 14 distinct sounds. All you have to do is run your guitar into it, and run its output to a flat frequency response powered speaker (or a headphone amp). The Flamma Preamp goes for an almost unbelievable $76 USD: Įverything, from very good amp simulations to speaker cab simulation, is already inside the Preamp. If this idea appeals to you, we can help you find a JFET that is still available, and which will work in this circuit. The J201 FET or MPF 102 FETs used in some of these old circuits may not be available any longer. If that's not to your taste, Runoff Groove has several other (more complex) JFET-based circuits that you can place ahead of the Digikey LM386 board. This still has no tone controls, and will sound midrange-dominant and dull until overdriven. A 10k trimpot will be less "twitchy" to set. 50k is really too large, and will end up set to nearly one extreme. I would suggest using a 10k trimpot for Rd, rather than a 50k one. A single JFET is a good start try using it configured as a Fetzer Valve ). If you want to use this with an electric guitar, you can easily add a simple preamp in front of it to sweeten the clean tones a little bit. But it might work well with an electro-acoustic guitar, which has its own onboard tone controls and preamp. It may also have an input impedance that's a little too low to be ideal for an electric guitar. It can be powered by an old USB charger (5V DC), or a 9V flat battery, or any small DC power supply up to 12 VDC, say, 9 V.īy itself, the board has no volume or tone controls, and will have the typical "too clean until it suddenly becomes too dirty" characteristic when you plug a guitar in. Since thoglette suggested a little toy amp: Digikey sells a nice little LM386 amp already built on a little PCB, ready to go: What sort of amp? A little toy one for living-room use? A big loud one that will make you a social pariah and set tongues wagging in the village/housing complex? RDH1 Danelectro Hodad I Mini Amp Electric Guitar Amplifier $109.What sort of guitar?
