Tools, Tones and Toys for Guitarists
Here’s another (and more complicated) amp emulator, and another great design from Brian Wampler. This one stacks JFET stages much like the Cranked AC. It emulates a dirty Fender tube amp with a 3-band tone stack. I added trimmers so it’s easier to bias the JFETs and it’s laid out for board mounted pots in … Read more
Here’s a simple little overdrive designed to emulate the old Vox 4 and 7 series amps (used by the likes of Jimmy Page and the Beatles). Pots are board mounted and it should fit in a 1590B easily. I’ve added a trimmer to bias the JFET at little easier. Schematic and voltages can be found … Read more
By popular demand, here’s the BE-OD from Friedman, one of the best Plexi in a box pedals around. Well, not Plexi really. It’s designed to emulate the Friedman Brown Eye tube amp head. Laid this one out for board mounted pots, and it will fit easily in a 1590BB. More info can be found on … Read more
Unrelated to the Angry Charlie circuit, the Charlie Brown emulates the brown sound of a JTM45 amp and is a variation on the zVex Box of Rock without the boost section. The input stage is an AMZ Mosfet Booster (replacing the SHO input stage of the Box of Rock to avoid crackle in the gain … Read more
Here’s the original Twin Twelve from JHS. It’s an emulator of the old Silvertone 1484 amp. Like a lot of amp emulators (including their Superbolt) it uses JFETs and an 18v charge pump. The schematic can be found here, and I added the charge pump from JHS’s Superbolt. Set the trimmers to around 9v and … Read more
Got a request for this one. It’s another Electra-derived overdrive, this time meant to sound like a Marshall. This should be an easy fit in a 1590A.
Got a request to do this one again but with board mounted pots. If you don’t know, it’s a FET emulation of the classic Supro 16T amp. More info, schematic and demos can be found on the Run Off Groove article.
The ROG Ginger is an amp emulator designed to sound like the classic Ampeg SB-12 Portaflex. So it’s intended for bass, but sounds good with a guitar as well. Schematic, sound clips, and more info can be found in the ROG article. It’s laid out for board mounted pots will fit easily in a 125B … Read more
I’ve gotten a few requests for the Mk. III and found several good stock layouts on FSB, so I thought I’d go with a slightly modified version of the DLS Mk. III. This has an added presence control, as well as an onboard charge pump. It’s designed for use in a 125B with top mounted … Read more
This is probably the biggest Marshall-in-a-box pedal out there (footprint-wise anyway). Originals use a +/- 12v supply with a transformer internally. I modified the power section with a +/-18v charge pump and will run off a normal +9v power supply. This saves room so you can use a smaller enclosure and gives more headroom to the effect. It … Read more
