2019, 15 Watts, 1 × 12” Speaker, Fromel Mod Upgrade

One of the most-beloved small combo amps in the world, the Blues Junior IV adds modified preamp circuitry, smoother-sounding spring reverb and improved aesthetics that any player is sure to appreciate.

From the factory, the Fender Blues Junior IV has a lot of potential, but with some select Fromel tweaks this amp can stand toe-to-toe with some of the finest boutique amps on the market.  After the mod, the amp boasts clean, sparkling top end, a huge sweep of mids and rich bass response.  The smooth, slightly compressed tube breakup stays articulate thanks to improved power filtering and upgraded tone caps.  The reverb is also made more lush and rich, with smoother decay.
