Tiamat - DIY Kit
Ships December 2026 - There are two Tiamat DIY kits - a full kit that includes everything and your choice of custom colors, and a PCB that includes all surface-mount components already soldered on & all six potentiometers. You will choose your custom colors via a survey I will send out when production begins.
The Tiamat overdrive takes the Dragon overdrive circuit an adds a clean blend, separate slope switches, and a switch to toggle between dynamic and saturated tones. It is my definitive overdrive design after 8 other versions across 18 years (three versions of the Proto OD, three versions of the Pale Horse, and two versions of the Dragon).
Controls
GAIN - sets the amount of gain in the overdrive circuit
DRIVE - sets the volume of the overdrive circuit
CLEAN - sets the volume of the clean tone blended into the drive circuit
COMP - sets the compression ratio and clipping type (middle position = diode lift)
HPF - sets the cutoff frequency of the pre-gain high-pass filter (affects bass response)
LPF - sets the cutoff frequency of the post-gain low-pass filter (affects treble response)
6 / 12 - sets the slope of each filter, from a gentle 6 dB per octave slope to a sharper 12 dB per octave.
SAT / DYN - selects between silicon clipping diodes for more saturation & sustain and mosfet transistors for better dynamics and greater overall output
IMPED - internal trimpot that sets the input impedance of the circuit
BUFF/TRUE - internal slide switch to select between true bypass and buffered bypass switching
LED - internal trimpot to set the brightness of the on/off LED indicator light
Warranty & Returns
Try any VFE Pedal risk-free for 30 days. Return it in new condition within the first 30 days for any reason and get a full refund!
All pedals assembled by VFE Pedals have a 1-year warranty on parts & labor. I will continue to offer repair service for out-of-warranty products indefinitely, even after I close down at the end of 2026.DIY Options
Full Kit - includes a fully assembled PCB, all other components, and your choice of paint color, knobs & LED.
PCB Only - includes PCB with surface-mount parts assembled and all the potentiometers. Does not include the jacks, switches, enclosure, knobs, and the nine through-hole components (6 film capacitors, 2 trimpots, and one slide switch). This will also include instructions & links on how to custom-make your enclosure (including graphic) using Tayda Electronic's services.
