Ampeg Sub Blaster
An old request. It is a biggie but I’m sure someone will tackle this anyway *cough, cough…Chris*.;-)

Bluff Chill Devices Ectoverb V1
Wanna build reverb without a bulky Belton brick? Bluff Chill Ectoverb got you covered. This one is using two PT2399 ICs in series to achieve a quite murky, spacey and lo-fi reverb. Schematic and more info HERE.
Catalinbread Montavillian Echo
Time to start rolling again… Here is a discontinued PT2399 based delay from Catalinbread with some filtering I haven’t seen anywhere else. Schematic is avaiable HERE.
VERO: How to Mount Vero in Pedal Enclosures
THE PROBLEM WITH VERO / STRIPBOARD LAYOUTS As much as I like a bit of vero (clearly), vero is not meant for commercial-scale production, at least in the modern sense. Unlike PCBs, where pots and switches can all be mounted on the board, thus providing a convenient way to hold the board in the enclosure, vero … Read more
MAD PROFESSOR: Stone Grey Distortion
Another CMOS based distortion, this time from Mad Professor – the Stone Grey Distortion. Details available on Aion FX, including schematic. Not that the original uses JFETS acting as diodes for clipping, which means very little if any difference when compared to a regular diode. If you want to use JFETS, details are in the Aion build … Read more
ELECTRO-HARMONIX: Hot Tubes
This is the CMOS version of the Electro-Harmonix Hot Tubes from the late seventies. I used the Aion FX schematic, which has some minor differences to the original. Smaller Drive pot, as it’s difficult to source pots over 1meg, and some improved power protection and filtering. ELECTRO-HARMONIX HOT TUBES – VERO LAYOUT HOT TUBES VIDEO DEMO
PETE CORNISH: TB-83 Treble Booster, Point to Point Layout
I followed a vaguely similar layout to the one pictured at the bottom of the post for the Pete Cornish TB-83 Treble Booster. This is a straight treble boost using a silicon transistor – it’s going to sound horrible into anything apart from a cranked valve amp, or maybe a valve based pedal. Given … Read more
GUILD: Brian May Box
The layout is for the Guild Brian May Box, which on the Guild schematic is marked as designed by Pete Cornish, but he has disputed this. There’s a massive write-up here on Fryer Guitars, including photos of inside Brian May’s Pete Cornish built pedal board, and inside a pretty vintage looking Pete Cornish treble boost, which … Read more
VOX: BM1 Escort Transistor Practice / Busking Amp
I just bought this rather beat-up Vox BM1 Escort practice amp from the seventies, or maybe early eighties today. I’m thinking seventies, as it doesn’t have an IEC power connector, and the grill cloth is the red/brown colour. The back panel looks different to the one on Vox showroom and other photos that I’ve seen, so … Read more
MI Audio Blues Boy Deluxe
Stumbled across the schematic for this one over on FSB and it seemed interesting enough. Should be able to squeeze it into a 1590B.
