PP-18 18W vintage plexi amplifier

Tone to DIY for... the Dominator/18W circuit is one of the best-sounding ever made

Get the classic vintage tone of the 'baby Bluesbreaker' in an easy-to-make guitar amp kit. The PP-18 uses the Normal channel circuit of the 18W Marshall of the mid to late '60s (itself 'borrowed' from the WEM Dominator). Like the original it has the simplest of preamps with just Tone and Volume controls and a no-frills cathode-biased 18W power stage, but the combination creates a dynamic and touch-responsive medium-gain amp that's perfect for blues and classic rock. At 18W, it's loud enough to keep up with most drummers for pub and small club gigs.

Superceded in 2015

I've left this page online as a reference for anyone in the future. The PP-18 has now been superceded by the P1800, which does everything the PP-18 did and a whole lot more. See here for full details: P1800 guitar amplifier kit.
