Really cool vintage pedals made in Japan by Maxon in the early 1980's. There are some youtube videos about the "01" series pedals and they are somewhat "sleepers" in that most them of them contain the same circuits as the "9"-series and other more sought after early Maxon/Ibanez pedals, but with a new look and more durable casing/FET switching that some of the earlier pedals lacked. I think they are quite cool and a nice change from the ubiquitous Tube Screamer. The Rock'n roll is liek a better Boss SD-2 and the JD-01 is very muff-like (v6).
OR-01 Rock'n Roll: $125 (switch is a little fucky and the price reflects that) Near Mint
JD-01 Jet Driver: $125 Very Good
Here is what Effects Freak has to say about these:
OR-01:
“The Maxon OR-01 Rock’n Roll Overdrive and Distortion is a two channel pedal like the Boss SD-2, but much, much better. Switches
between overdrive (“rhythm”) and distortion (“lead”) when the pedal is pressed, or operates with remote footswitch. Uses 9-Volt battery, or Ibanez AC-109/Boss PSA Adaptor.”
“Made in Japan by Maxon, who made all the famous Ibanez pedals in the
1980s. This is from the “01” series, only released in Japan. RHYTHM channel is a clean sounding overdrive with a little more gain than a TS-808, but a lot more full-frequency. LEAD channel is fat sounding, highly saturated lead boost, similar to SM9 Super
Metal but smoother and not as rubbery. More like a modded JCM800 type sound.”
JD-01:
“The rare and vintage Maxon JD-01 Jet Driver Distortion. Part of the increasingly collectable “Zero-One” series of Maxon pedals from the 1980s, never released in the US. If you like the famous nine series, the “01” series was comparable, but with much more reliable switches.”
“What’s it sound like? It’s very high gain, and the sustain just keeps going and going. There was no comparable pedal in the “9” series...
“These are more like the Maxon D&S series of pedals. These have a narrower Q on the “Personality” or tone control which has the effect of having a broader sweep. Basically a Big Muff clone with a more usable tone control. This pedal also has more gain than my early Maxon D&S with the Sustain T control, but I can get both to sound pretty close to one another. That pedal is the same as the Ibanez OD-850 pedal.
