Tools, Tones and Toys for Guitarists
Here’s a variation of the classic Tone Bender Mk II Professional from ProAnalog Devices. It uses PNP transistors, so you’ll have to use either a battery or voltage inverter to daisy chain this with other pedals. It seems they’ve used several different transistors, but they’re outlined in the schematic from Scotty himself. Easy fit in … Read more
Got a request for the DI portion of the Hartke LH1000 bass amp. This is more or less that, but with a simplified power section. In the amp this runs off a bipolar 15 volt supply, but I would think it would also work with regular 9 volt supply. There’s not an unbalanced output, but … Read more
Here’s a simple MOSFET-based booster circuit that’d be a nice alternative to the SHO. Should fit in a 1590A. FYI, the 1N4739 diode in the layout is a 9.1v zener. Here’s the schematic for reference.
Gotten a couple requests for this one. Here’s Bajaman’s second take at his AFD circuit with a better frequency response than the first AFD. More info here on FSB. Should fit nicely in a 1590B.
Got a request for this one for Fuzz Friday. The Tone Bender Mk.II Professional is essentially a Fuzz Face with an extra gain stage up front. The Fuzz-Bender basically puts the extra gain stage of the Mk. II on a switch, allowing you to more or less switch between a Tone Bender and a Fuzz … Read more
I traced this one a while back and created the Lawn Darts PCB over on the store from it. About time I made a perf and etch layout. If a Rangemaster and an Electra ever got together and had a baby, the Arrows would be the baby. Should be an easy fit in a 1590A … Read more
Stumbled across this schematic on FSB. It’s a buffer/EQ/preamp for peizo pickups, specifically all Barcus-Berry electret microphone systems. I figured most would be building this into an instrument and not a pedal, so all the pots are off-board. If you’re planning on running it only off a 9v battery, you cab get away without the … Read more
This one was requested ages ago and I got halfway through laying it out, and then promptly forgot about it. It’s a power amp/speaker cabinet simulator, emulating a SLO power amp and a couple different speaker cabinets based on the value used for CX (see schematic for values). This layout follows the Rev4 schematic from the … Read more
Happy Fuzz Friday everyone! Got a request for this one put forth on FSB. It’s based on the ThroBak sTone Bender, which itself is just a straight clone of the Tone Bender Mk II Professional. The layout is setup for positive ground and PNP transistors. You can use a voltage inverter daughter board or flip any polarized … Read more
Original info: “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 … Read more
