DIY drive pedal (BJT silicon) + Celestion Eight 15 IR

This is a re-upload of my previously shared model, this time with much more balanced frequency response. PEDAL DIY custom circuit based on four 2SC1815 transistors, some capacitors, diodes, resistors and that's it, no OP-amps. Was powered with a 9V alkaline battery during the capture. CAB (as separate IR wav file) Celestion Eight 15, 8" 16 ohm guitar speaker in a double-sided open-back cardboard 18x16x7" box, Zoom H1n used as mic (~1 inch from the cap center, straight angle). For IR capture I've used PAM8403 as amp (powered with 3xAAA alkalines) and REW & Audacity software. Feel free to use the pedal with any other IR.
