83 Drive is a new dual overdrive guitar pedal and the ultimate tone machine, providing a variety of delicious tones. It can be used as an always on drive tone all the way to a mid boosting lead tone. Our take on the legendary K-style overdrive and the Black Box Bluesbreaker, it features two independent overdrives, giving you two classic drive sounds favored by many guitarists in one enclosure. Our inspiration for the ’83 Drive came from our enthusiasm for each of the two pedals used alone and by how amazing they sounded when stacked. Both pedals have played an important part in the live guitar tones of John Mayer through the years, as the pre drive he stacks into his TS10 to obtain his lead tone. We decided for ’83 Drive as the number 83 is a significant number to JM. We have recreated the circuits staying true to the originals, but we've made the BB circuit true bypass with additional switching options for tweaking and increased the headroom up to 18 Volts. We have kept the buffer in on the K-style side of the circuit. The ’83 Drive is divided into a side A (left) and a side B (right), separated by the order toggle switch in the middle which flips the internal order of the effects and hence the signal path from guitar to amp. Side A features the BB-style circuit with external knobs for GAIN, TONE, VOLUME and a three position toggle switch labeled LOWS. The lows switch changes the bass response of the circuit. Internally you find four sets of dip switches (gain, soft clipping, symmetrical/asymmetrical clipping, hard clipping) that further enables you to tweak your tone. The side B features the K-style circuit with external knobs for GAIN, TREBLE, OUTPUT and a two position toggle switch labeled CLIPPING. The clipping switch toggles between a pair of germanium or schottky clipping diodes. Both sides can be used separately or stacked. Features: Side A (left) - Replica of the circuit of the first BB1 - Black Box Blues Breaker circuit. - Op amp supply voltage increased to 18 Volt for more headroom. - External three position lows toggle switch for extended low frequency response - Four sets of internal dip switches for extended tweaking * Distortion/hard clipping (switch 1-2) * Clean boost/Overdrive/soft clipping (switch 3-4) * Symmetrical-Asymmetrical clipping (switch 5-6) * Gain: Low/medium/high (switch 7-8) Side B (Right) - Exact replica of the K-circuit. - External two position Clipping switch to switch between a pair of Germanium - or a pair of Schottky clipping diodes in the overdrive gain stage. - The germanium diodes we use are original russisk NOS D9B (as long as our stock lasts) External switch to choose in which order the signal passes through the two circuits. The ’83 Drive is built using carefully selected top shelf components:: - VISHAY 1% metalfilm resistors - WIMA MKP10, MKS4 and FKP2 film capacitors - no electrolytes in the audio circuit. - VIMEX sealed potentiometers - CARLING Footswitch - CKK and TAIWAY toggle switches - PURE TONE MULTI-CONTACT 1/4 JACK - Silver plated teflon insulated cable for internal wiring. - US made DAVIES MOULDING 1470 knobs - Dimension: 5.72 in x 4.77 in x 1.39 in (145 mm x 121 mm x 35 mm)
