Pete Cornish BD-1 Bass Driver

The BD-1™ is not a variant of any existing product but a completely new and original design.
Initially designed for Bass Guitar, the BD-1™ has also proved very popular with Baritone Guitars and dropped tuned Guitars when heavy overdrive is required at the lower frequencies of these instruments.

With Germanium components for added musicality this new design features full Bottom-End retention and is flat down to below the
bottom B on five string basses.

The tone controls are very powerful and feature an active boost and cut with a combined range of 34dB at maximum settings.
Being active, the two tone bands can be both cut and boosted as desired with the zero or neutral point being 12 o'clock on each control knob. I have included a second fixed gain linear boost stage after the tone circuit to compensate for any reduction in overall volume when the tones are in ""cut"" mode.

The benefits of this active tone circuit, compared to the usual passive (Cut only) tone circuit is that the two bands are completely independent and there is no
interaction between the Bass and Treble tone controls.

An output Master Volume is included to allow for perfect matching between bypassed and overdriven and EQ’d signal level and there is plenty of signal headroom available to overdrive amp inputs if required.

Our well established Class A input buffer and radio frequency suppressor is, of course, included and the output buffer impedance is low to easily drive long cables or other loads without loss of signal or tone.

TECHNICAL SPECIFICATIONS:

• Overall boost with Gain = 100% and Volume = 100% is +55 dB {Reference: input = -52dBm(V) and output = +3dBm(V)}
• Overall boost with Gain = 0% and Volume = 100% is +19 dB {Reference: input = -16dBm(V) and output = +3dBm(V)}
• The above with Bass and Treble set to 50% (Neutral point).
• Bass Control range +16/-13dB @ 30Hz
• Treble Control range +12/-18dB @ 3KHz
• Maximum signal output with Volume 100% is +10dBm(V)/ 2.5vrms/6v Peak to Peak (at clip point)
