This is what i was looking at for a direct replacement for one of my three bands, a Four band with the mid high & low.
[quote]BTB MMSR 4 Band Preamp by John East 3 knob, Volume - Bass - Treble - Mid/MidSweep
£157.50 Chrome, £172.50 with plate
The BTB-MMSR 4 Knob, including Mid Sweep, has been designed with characteristics very similar to the original MM Stingray© 2 Band EQ, but is not a copy of the original circuit. The original used a single op-amp chip (single amplifier stage in the form of a chip) for both bass and treble circuits, whereas this unit utilises a more modern dual op-amp chip (two amplifiers stages in a chip). The bass and treble are stacked which allows inclusion of a mid sweep, along with original MM style bass and treble, on a 4 knob plate. When the mid boost/cut is centered, its effect is neutral and the EQ is purely late 70s MM style.
This unit is supplied fully wired, including 3 single pots, 1 stacked pot, knobs, jack and battery clip, which may be spliced into an existing battery box, as would be available, in most cases.

POWER REQUIREMENTS: 9-18V, 2.5mA[/quote]
The power requirements 9-18V ? silly question (well not a silly question cause i don't no the answer to it) is it 9V or 18V ?. Would it run happily of one 9V battery but just for not as long as if it had the full 18V supply constantly to it, or would it need the full 18V (2x 9v battery fitted) to get the full potential out of it ?
