White (Used)

All photos are the actual pedal. No box or manuals. From Spiral Electric FX: The White Spiral Boost is a dirty boost and the result of my exploration of various JFET circuits initially inspired by Jimmy Page’s use of the Barcus Berry Preamp.  While Page is only known to have used it on acoustic, I found that the BB 1330-1, and the simpler BB 1330S, work great with electric guitars that have low-output pickups and as a general boost circuit.  The White Spiral circuit has evolved over time to become a hybrid circuit with bits of the BB 1330S, National Semiconductor Mu-Amp, and the Yellow Spiral.  The White Spiral uses a dual JFET for amplification, the Grit is a combination of JFET and Silicon clipping, the Girth control comes from the Yellow Spiral but with a twist, the White also has 18v internal operation to provide increased headroom. The location of the Girth Control in the circuit is user-definable by the Alpha/Omega two-way toggle.  In the Alpha (A - Left) position the Girth contr
