Here's a collection of vero (stripboard) and tagboard guitar and bass effect layouts that we have put together covering many classic and popular effects in growing numbers. Many of these have been posted on freestompboxes.org, so check that site out for great discussions on building your own effect pedals. Enjoy the builds and please also visit us on Facebook and Twitter
Ram The Manparts is a LM386 (a power amp
chip) overdrive that we built to allow guitarists and bassists to not
only drive an amp HARD, but also to add some textures and features to
stand out! The voltage sag allows the user to drop the voltage below 9V,
creating a glitchy, sputter, Velcro-like sound. Keep it clean, make it
grindier/heavier, or make it glitchy…the choice is yours, dude.
The pedal has since been discontinued and not the cheapest when buying used if you can find them.
"ZUUL is the most transparent noise gate on the market! Studio quality specifications with simple straight forward operation.The ZUUL’s threshold knob also controls the dynamics of the gate
circuit. Perfect for guitar, bass or any signal source as it has studio
quality specifications. Use in front of an amplifier or in a series
effects loop. Dual colour LED for visual feedback gating action: Green =
Open, Orange = Closed, Off = Bypass. The KEY input signal can be
directly from your guitar (ex. split from ROACH or SPLIFF) or other
signal source which lets you go from clean to high gain without changing
the Threshold knob. This powerful feature lets you control the gate
with a different signal than what flows through the input/output jacks
of the ZUUL. Side switch or internal jumper to change the threshold
range if you are injecting a large signal into the input and not using
the key input"

Strange Master treble booster now includes both Germanium and Silicon
transistors. These transistors are switchable so the user can now get
classic Dallas Rangemaster treble booster Germanium tones and higher
gain Silicon treble booster tones from one pedal!
ThroBak guitar effects pedals offers another classic Signature Sound effect with the Strange Master Treble Booster, a recreation of the Germanium Dallas Rangemaster Treble Booster used by Eric Clapton, Brian May and Tony Iommi.
keeping with our ThroBak Guitar effects pedals Signature Sound
philosophy Strange Master treble booster offers user adjustments to
shape the sound of this effect. Jimmy Page, Jimi Hendrix and Brian May
had Roger Mayer and Peter Cornish customize their effects to create
their own signature sound. We give this control to you.
far as we can tell we are the only company offering a Dallas Range
Master clone with a bias adjustment. This allows you to change the
character of treble boost from loose to tight. Switchable range allows
treble boost and mid boost germanium distortion. Recreate the Clapton
Beano tone or the singing overdrive of Brian May to the growl of Tony
Iommi with this pedal, its all in there.
Basically, the Strange Master is a Rangemaster with a switch allowing you to selecting between 2 input caps (Treble and Full)
and another switch to select between transistors (Germanium and Silicon), and a bias pot to adjust the bias either between the germanium and silicon transistors or give it a little grit.
Keep in mind that the gain of the transistors is going to be paramount in getting it to sound good. I would suggest looking for gains in the 100-120 hFE range
for the germanium (just like a regular rangemaster), and something around 250 hFE for the silicon. Also you can play with the input and output caps to get more or less bass. You can also change the Hi/Low switch for a pot to give you a sweep between the 2 input caps.
Brad of Creepy Fingers posted about his build of the old SRS EQ/Exciter pedal with a little mod to allow for gain control. The SRS EQ/Exciter is basically a Fuzz Face with a buffer and a mid control. All I can say is this thing sounds HUGE!!!!
