Re: Onboard boost into a fuzz pedal?
active system = low impedance.
Not ideal for fuzz faces or octavias. You will get a thin, buzzy weak sound when the fuzz is engaged.
I cant say ive used a clapton circuit, but i have run my guitar thru a nice low impedance buffer from t1m, also tried using the buffer in my morley wah and have also run a tubecreamer type thing ahead of it. The fuzz faces that i own all sounded anaemic after all of these buffers.
If you really want to use the onboard stuff for boost, you might find that a big muff style of fuzz because they are pretty forgiving with any input. Obviously its not going to sound the same as an octavia based fuzz tho. Something like the MI neo fuzz (if you like germanium) or GI fuzz (if you like silicon) might suit you because they have onboard buffering and a LOAD control that allows you to use any style of pickup with it or place it anywhere in the chain. Perhaps one of those MXR classic fuzzes will do the job because they have a buffer built in that keeps the fuzz circuit happy even with a a low impedance signal.
Another way to do it would be to use one of those foxxrox fuzz friendly buffers installed into a wah, or perhaps a one of the teese wahs with a fuzz friendly buffer. There are various options.
Another option is to eschew the installation of the onboard boost, and use an old skool boost like a rangemaster or similar from analogman or keeley etc. These work fine with fuzz faces or octavias and you can get the benfit of it with all your axes.
