While the Stilettos arethe first amplifier in the
MESA Family that features exclusively the EL34 type power tube, it is no less endowed
with the patented features and refinements than its
MESA siblings utilizing 6L6 type pentodes for power production. Years of scrutiny
and testing of the available ‘34‘s was incorporated into the long process of R&D to ensure reliable performance while we were extract

ing our measure of this revered tubes’ golden elixir of harmonic bliss.
The ACE delivers all the vintage voodoo power-clip characteristics of the best classic British EL34 amps, and yet goes far beyond
those gems in terms of gain, expression, nuance and flexibility to put a new standard in place in the realm of EL Based circuits.
