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 MASTER 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 can also get a cool GATED sound like a Tonebender MKI, by setting the MASTER BIAS a bit lower. Lately we are setting the internal knob a bit lower so that you can get these sounds by turning the center BIAS knob down all the way. It still allows for normal sounds by turning the bias up.

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. These clean up with a nice crunchy sound when you turn the guitar or the clean trimpot down. 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.

These have an interesting, gradual cleanup, unlike a Fuzz Face which tends to get too clean too fast. Back a Tele down anywhere from 4-7 on it's volume knob, and with your picking attack you can go from almost clean to awesome Tweed amp distortion sounds up to a fuzzy tube amp distortion. Very natural sounding! The white CLEAN trimpot can be used to preset this less saturated, crunchy distortion sound.

I get asked about the differences between this and our MKIV Sun Bender a lot. The MK1.5 is more raw and 1960s sounding, with a BIAS knob. MKIV is more saturated and early 1970s sounding, and has a tone control that can go from thick to thin and trebly.

We have always used New Old Stock British Mullard transistors in this pedal:

In 2019 we got some outstanding Mullard CV-type military tested transistors, which are very consistent and sound great! These are dated 6927, made the 27th week or 1969, what a great era!!!

The on/off FUZZ pot is optional 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.

TOP JACKS : we may have a few with top jacks, ask if interested.

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, just different. 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.

Here is what an original MK1.5 looks like, this rare pedal was on ebay at the end of 2012 for $5,000 but got no bids.

5 of 5 Hands on Search December 29, 2019
Reviewer: Brett Huhn from Columbia, MD United States  
My guitar teacher loved this circuit, and when I heard it, on an old 'Soul Bender, I fell for it. I since bought 4 different versions of it from popular sellers. This thing is absolutely what I had first envisioned having on my board. Perfect to crank and use my volume knob on. I have Treble Bleeds in my guitars, and the MK 1.5 works well with them and my Supro amp. I can play about anything on it, clean to dirty, Country to Ozzy, (with a boost, after). It will be on my board, until....... This is what I thought it should be with the jaggedness if I want it and its responsiveness to my touch and volume choices. The EQ on my amp can make this thing dance, and it is 'infective' to play, as in all guitars, PAFs, to D'Armond, to Tele to vintage wax potted '59 Humbuckers. Search Over, thanks to aNaLoG.Man!

5 of 5 Sunbender MK1.5 October 2, 2019
Reviewer: shane hartline from San Diego  
I don’t k ow how to put in words how this pedal feels and sounds but it’s one of the most inspiring and dynamic fuzz that I have played. It sounds great with Single coils but IMO it shines with Humbuckers. It cleans up beautifully and cuts like knife in a live mix. Well worth the price of admission.

5 of 5 Mk1.5 is a ten March 19, 2017
Reviewer: Todd from San Carlos, CA United States  
I've never played a vintage guitar through a vintage amp, and I've never owned any vintage effects. I have an ok ear and moderate guitar ability. I have played for 30 years and what keeps me playing is inspiration. You can't buy it, but it is around if you look for it.  The sound coming from the speaker and into your ear-straight to your mind (or soul).  I was inspired playing through the Sunbender, and I notice that happens a lot with Analogman pedals. I don't need vintage this or that, and I'll never be the next (fill in the blank), but this is why I play guitar.  Thanks for inspiring me, Mike. And to whomever reads this review, maybe you can't buy inspiration, but you might find it here just the same.

5 of 5 Tone Heaven July 15, 2016
Reviewer: Joao Brandao from sao paulo, sao paulo Brazil  
Pretty much tone heaven with my Les Paul in the clean channel of a Two Rock Custom Reverb. You will get the classic tone from so many records! Can´t go wrong with Mike´s products!

5 of 5 The cosmos is better with a Sun Bender February 29, 2016
Reviewer: Gary Luparello from Mint Hill, NC United States  
Been putting my new Sun Bender through the motions, and it is getting me back into the days of 70's King Crimson and other favorite Italian Prog guitar sounds. AM pedals always seem to sound as advertised, and the Sun Bender is no exception. The pair of germanium transistors really do offer plenty of gain on tap and the bias knob shapes the mark II tonality exactly where I want it. It has more treble and gain than a sunface NKT. Being a ProgRock player, I am finding many uses for this very musical pedal. Authentic 70's fuzz guitar tones.
