Class A Overdrive Mini
99 125 $99.00 - $125.00
Formerly the "Jelly Roll", the Class A Overdrive is based on a hot-rodded late 1950's Supro. The amp was modified with a single ended 6973 power tube instead of the usual 6V6. The output transformer was taken from one of 6973 driven reverb units. It was also modified to closer replicate the preamp of the larger 1624T model. It was essentially a single ended version of a 1624T.
The Class A Overdrive uses JFET gain stages desinged around the amp. I chose JFETs for their warm, but clear character when overdriven and superb dynamics which you will find the Class A Overdrive to be full of. The tones range from fat jazzy clean tones to a crunchy classic rock sound with hints of a British timbre. Unlike some of my other pedals, the Class A Overdrive isn't geared towards any particular recorded or artist's tone. However you'll find sonic shades of Keith Richards, Page, Townshend and many more.
The Class A Overdrive has controls for volume, drive, and treble.
- The volume control sets the output level of the pedal. Unity gain is around 10 o' clock depending on where the drive level is set and it only gets louder from there making it usable as a boost too.
- The drive control is what would be the volume control on the actual amp. At its minimum, the tone is clean. As you turn the dial up to about noon you get that clean but dirty sound, think Communication Breakdown. Turn the drive all the way up and you'll find a harmonic rich overdriven tone. The drive levels are accurate compared to the acutal amp. You have clean, low gain, and medium gain.
- The tone control is a simple, but effective high cut filter. Same type found on the amp and numerous other Supro/Valco amps for that matter. Turn it down and you'll decrease the high end content, turn it up and it gets brighter. You will find the tone and drive controls are interactive.
- A three-way mini toggle switch mimics the three different inputs on the amp. In the mid position, the sound is the fullest tone. Flipping the switch towards the knobs gives a bass cut and an overall brighter tone; very useful with humbuckers. The third position sits sonically between the others, offering a slight bass cut resulting in a well rounded tone.
- The Class A Overdrive can run on 18 volts as well. As you increase the voltage, the headroom and output level increase.
Lead time for both sizes is 1-2 weeks
