The Saguaro (sa-wah-ro) boost is a single control overdrive boost. Think single knob K-type boost. The control makes a rustling sound as it's adjusted and only when it's being adjusted. This is by design as the control adjusted multiple circuit parameters simultaneously. There is nothing wrong with the control pot.
It can go from clean unity gain at minimum to moderately overdriven with pushed mids at maximum. The Saguaro has 24dB of boost available to drive edge of breakup amps or other drive type pedals into sweet signing sustain. As the control of the Saguaro is increased the EQ of the circuit is altered from flat at minimum to pushed mids at maximum. Keeping the lows intact and tight while allowing the harmonics to fill in the highs. Several customers have noted a striking similarity between the Saguaro and the Kl*n Centaur as an edge of breakup booster.
It's a great circuit to put in front of your vintage amplifier to get a sweet fat breakup out of it or in front of any overdrive/distortion pedal to get a more organic tone and feel. Great for soloing or making up for low level vintage pickups. Size - L 3.625" x W 1.5" x H 2" Solid artisan hand built construction, right here in Arizona USA means attention to detail, high quality and long life. I personally build, sign and date each Saguaro.
