Twangtone by BSM
|Buzzbender Bass Fuzz||center positive|
Notes: BSM offers an impressive – almost bewildering – range of trebleboosters. Most units are battery only, with a current draw of less than 1 mA. This list contains only the units that have adapter jacks.
Voltage is 9vDC unless otherwise noted. Some units have a note that indicates the pedal is negative ground, which leads to the assumption that the others are positive ground and therefore require an isolated/separate power source. Not that it matters much which is which – all these units should have an isolated source, regardless.
All adapter jacks (except the Twangtone series Buzzbender) are regular center negative, 2.1mm type.
