Tools, Tones and Toys for Guitarists
Layout for the first version of Small Stone which was produced between 1974(?) and 1978. Layout is based on schematic from Lectric Fx Note that original had long gone obsolete 8 pin OTA chips so this layout is modernized for easy to get LM13700s.
Aions Ares project which is based on Echoplex EP-3 Pre Amp which includes an onboard voltage doubler for more headroom. Schematic and info on J FET selection avaiable HERE. ‘Note that there is two ground connections on the board, the purpose is to reduce any potential noise from the charge pump. Those wires can be … Read more
Similar to MXR 45 phaser but the pesky J FETs is replaced by a CD4007 chip so no transistor matching is required. Schematic avaiable HERE
A simple delay with both subtle reverb tones as well as oscillation reverb…. Schematic HERE
Requested by Alltrax74, a phaser based on MXR Phase 90 with some bells and whistles. Schematic is avaiable HERE Note that the J FETs should be matched for best effect and CLR 1 value is 47k in the schematic but you could probably go lower if you not using a super bright LED
A requested circuit but bear in mind that it is rather big, has an onboard charge pump for 15v-15v operation, and has a quite complicated setup due to five multiturn trimmers. I’ve omitted the (for now) the Osc, Pitch, Carrier and Modulation jacks but might add it later on if is requested but it will … Read more
