Hello. I'm trying to share some information
about moding and building music related hardware.
Here's what you'll find here:
Schematics of classic effects and amps
that I have traced or that I have at my archives (will
try not to repeat circuits you can find elsewhere);
Schematics of effects and mods that I
have designed;
General information about electronics
(applied to music).
In order not to be repetitive, whenever I
talk about subjects like the Fuzz Face, Tube Screamer or Bassman
'59, I will put links to people on the net that have done VERY,
VERY good jobs about them. Take a look at AMPAGE's resources, and search for GEO, DMZ, Leper's Schematics, Aron's Stompbox, etc. However, I will put on this page mods and
tips about these subjects if I think they're original (= I didn't
see it nowhere else).
Now, hands at work. Here are the first
topics:
One transistor Theremin. NEW! Photos and sound sample.
Brit Face - three mods (with sound samples)
for the FF: a British/Classic switch, how to get rid of
the "noise gate" side effect and how to make
the FF insensitive to temperature changes.
Fat Screamer - A mod to the tube screamer that will give
you more bottom end when using it as a booster and still
roll off the bass to prevent inter modulation when you're
distorting the unit.Sound
sample: the Fat screamer doing some harm to the input of
a Fender clone tube amp.
Use your effects with AC/DC adapters
of any polarity. - soon
How to make a Reactive Load for your amp that simulates YOUR speakers.
Listen to me playing! "Odd" (589K)
is an instrumental tune which alternates 5/4 with 4/4 time
signatures. "Cabala" (2,4M) is a fusion
instrumental. "Noite" ("Night") (1,8M) is
a blues with lyrics in portuguese. The three compositions are mine.
All sequences programmed by me, all instruments played by me.
What's NEW! - The AR-15 power supply schematic is now on line. In the miscellaneous schematics section, the BOSS SD-1 schematic has some capacitor values corrected. There's also a pickup switching scheme for two humbuckers and a PSPICE model for the 12AX7 that takes in account the "bending" of the curves for low plate voltages.
