Starting to build the Vibe-R8R.
This is the initial soldering of the resistors.
The Enclosure and board are from Argenziano Effetti.
The resistors are Precision Resistive Products 1/2W 1% PR9372 Series.
Hendrix. Trower. Vaugn. Gilmour.
Doppler, anyone?
I have a prototype Vibe-R8R in the works.
Custom enclosure on the way from Poland.
Custom bare PCB on the way from Spain.
Based on the classic ’60s Uni-Vibe from Shin-Ei.
More than 50 Dale CMF55 mil-spec precision resistors.
Elna silk audio capacitors.
Fischer & Tausche aluminum power capacitors.
Silver-plated mil-spec teflon-insulated stranded wire.
All lovingly soldered here in New Hope by hand, by me.
John Diaz getting some lush tones out of our Stereo Pi pedal.
His unique style reminds me of a blend of Carlos Santana and Robert Fripp.
Formerly with the Antics, I’m looking forward to seeing him gigging again soon.
John also commissioned and plays our 36 Watt “Ballbreaker” amp.
