SM-01 (Super Metal)

Effect Information

“The late 1980s Maxon SM-01 contains dual JRC4558D and MC1458P op amps. This effect was a repackaging of the early 80s SM-9 Super Metal (Ibanez and Maxon branded). It can be a stand alone distortion pedal with plenty of available gain.  The equalization controls are from left to right; high, mid, low.  These
controls operate fully independent of one another, so when the low end
is boosted, the mid and treble remain unaffected and vise-versa, which
provides great tonal flexibility.  A word about these controls; they
are very powerful.  High, mid, and bass can either be very
substantially boosted or cut.”

Not much information is available on this rare Maxon but here is one review at NoiseGuide.
