| Description |
Vintage Rockman Tom Scholz Power Soak Model II Amplifier Attenuator
Here we have a vintage pre-owned Power Soak Model II amplifier attentuaor from iconic guitarist and guitar equipment engineer Tom Scholz. This unit dates to 1982 and is in very good condition for it's age.
The Power Soak was originally designed by Scholz when he and his band 'Boston' were recording their debut album. It was made so they could get a cranked tone out of their Marshall stacks responsible studio volumes. The Power Soak also included a master volume control so the desired tone can be achieved and then volume set afterwards.
The personal prototypes used by Scholz from 1975 (?) till 1980 allowed the new-born company SR&D to issue its first product, the Power-Soak, in the end of 1980. The first commercial ads appeared in 1981, and were rather product oriented: the Power-Soak is a tool, not a toy, and it really solves a problem for the guitarist.
An updated version of the original Power-Soak, known as 'Model II', was issued in the end of 1981: it has an extra switch made to adapt the Power-Soak to the solid-state amps (though its primary target is the tube amps market). The resistors network was tweaked a little, for a more precise attenuation control (?). No audible sonic difference with Model I.
Discontinued in 1982 when the Rockman headphones amp was created, the Power-Soak was re-issued in 1992 as a PS-III model: the difference is in the jack positions (rear panel on the re-issue, front panel on the original). The solid-state switch has disappeared, and the manual says that the PS-3 can be used both with solid-state and tubes amps. The impedance switch has two positions only (4 & 8 ohms), but 16 ohms amps can be used at the 8 ohms setting.
How many Power-Soaks were built? Around 10,000, if we refer to the number of eBay transactions per year. That's consistent with the serial number of a Power Soak I own, which has the serial number 82-2816 (approximately 3500 per year).
