Mystic Miles - Dumble preamp
Mystic Miles - Dumble preamp
When it comes to boutique amplifiers, the Dumble name is probably one of the most icnoic and talked about, yet equally shrouded in mystery. The Overdrive Special model in particular has been used by several iconic artists including SRV, Eric Johnson, Larry Carlton, John Mayer, Robben Ford, Santana, Joe Bonamassa, and the list goes on and on.
Mystic Miles is my take on capturing the legendary tones of the Overdrive Special in a pedal format. The design features JFET's which are excellent for emulating vaccum tubes at a much lower voltage. Controls are as you would find on the original amps and are very interactive. Drive, Master Volume, 3 band EQ and Presence.
In addition, there are two toggle switches to provide a range of tones.
V - Volume, G- Gain, P - Presence, B - Bass, M - Mid, T - Treb
Br - Bright Cap toggle, Deep - Mid boost toggle
The "Br" switch essentially adds or remove the Bright cap. Just like an actual amp, the difference can be heard on the lower to medium settings of Gain. Selecting Cap in gives you a sparkling chimey tone at lower gain settings that is great for cleans or crunch. With the cap out, it gives you a fuller range crunch great for rythms.
The "Deep" switch introduces a Mid boost which is great for leads as well as chunky rythms.
Since this is a preamp unit, it can either be used on a pedal board in signal chain as a drive, or you can run it directly into the effects loop of your favourite amp. Another way to use it is to run it directly into your DAW followed by speaker IR's for recording. Even though it has enough gain on top, you can drive it even harder by using an OD in front, as you would with an actual tube amp.This pedal runs on standard 9V center negative DC supplies. It can also be run anywhere from 9-18V for more headroom.
