Previously known as the 33v Preamp by TMD, this updated version now goes by a more fitting THE name, PentaDemon Boost.

When updating this product I got my hands on the classic TC Electronics Integrated Preamp that many low tune bands have now used to tighten their bottom end and slam the front of their amp. After tracing it, I sat down to decide to keep it pure as possible with the EQ is left intact like the original unit for a much more flexible device. I've cleaned up parts of the original circuit as well as separated the grounds for the lowest noise possible. Like any boost if you have noise in your line it will be in the boosted signal but it’s not plagued by the noise issues as so many flawed clones.  

Compare to 33, Dirty Tree, or the other umpteen versions.
