Bartolini Vintage Quad Buffer (TQB), Four Channels, 9V Only

The four separate buffers in the TQB Quad Buffer can reduce electronic noise levels in instruments with passive pickups and some of our on-board preamps. Each buffer in the TQB is a low noise amplifier with a gain of 1, an input impedance of 270 kOhms and an output impedance of less than 10 kOhms. This low output impedance allows the TQB to drive 25 kOhm Volume or Blend controls very easily. This configuration was used in many instruments by Michael Tobias in the mid-late 80's. The tone quality was similar to that of the coils in parallel but with higher definition and lower noise.

• 4 channel buffer preamp for electric bass
• discontinued NOS equipment (not ROHS-compliant)
• used in some old Tobias era basses to buffer each individual coil of two humbuckers
• input impedance 270 kOhm
• output impedance 10 kOhm
• gain factor 1
• supports 9V operation only, do not connect to 18V
• power supply via 1 x 9V battery (not included)
