Product Description

The Analog Man Sun Bender MK1.5 custom built fuzz pedal. Early two transistor Tone Bender circuit.

This is an exact Tonebender MK1.5 pedal topology, but with a few part values tweaked a bit for better performance. We made the BIAS resistor adjustable on the BIAS knob in the center of the pedal, as there are some great sounds to be had by running higher bias than normal. It gets brighter and cuts through better when it's overbiased. Some people like the bias lower for a deeper but softer sound. There is also a blue BIAS trimpot inside to set the center setting of the BIAS knob. We set it at 5V at the shop and normally you should not need to use that. But at high or low temperatures it can come in handy if the bias changes.These are quite temperature sensitive, so if you usually play in cool or warm temperatures, please let us know and we can choose one for you that works well when colder or warmer than normal (our normal is about 73F or 23C degrees)

We also changed a capacitor value slightly to make it sound and work better. In addition, we added the CLEAN trimpot like our Sun Face, as it helps preset the pedal for cleaner, or less bassy tones that some people like, especially with hotter pickups. We recently changed a resistor value slightly to make them a bit louder. Some people, especially with humbuckers, were complaining that the normal MK1.5 was not loud enough for them, so this should help. Simply copying a schematic would have been easier, but we want to make the pedal as great sounding as possible, and allow it to work with various guitars and amps.

So this is our updated take on a MK1.5 Tonebender.

The FUZZ knob is more useful on the Sun Bender than on a Fuzz Face/Sun Face, you can turn it down as much as you like and still get great tones.

We have always used New Old Stock British Mullard transistors in this pedal:
This version includes the on/off FUZZ pot to allow disconnecting the battery without having to unplug the pedal, great when mounted in the middle of a pedalboard. Turn it down all the way and it CLICKS and turns off the power.

SIZE : MXR style box, 2 5/16" x 4 5/16" 1290 / 1590B

We decided to make this 2-transistor MK1.5 instead of the 3-transistor MK-II as we don't have many of these awesome British NOS Mullard transistors. Also we tested them side by side and found that an average MK-II really didn't sound better. The MK1.5 is a bit easier to make consistent but they can still be tough as the circuit with NOS Mullards is very finicky. The MK-II is about the same circuit as an old Marshall Supa-Fuzz, you can hear the comparison below.
