DredgeMore OverDrive++ 2025 & NOS 1995

The DredgeMore Pedal is an ultra versatile overdrive/distortion pedal that has a few more features that the original one knob Dredge OD.  Way more knobs == Way more tonal variations! 

This pedal uses an old Mil-Std 883B, hermetically sealed op-amp for the heart of the OD circuit.  I have about 100 of these parts left, and there is no easy way to find them these days from reliable sources.  I'll probably only build 80 of the 2025 units in total before diving into an update with non-obsolete parts.  Well, unless I find a cache of them somewhere, somehow. The NOS 1995 version is hand wired and built using boards that were sourced in 1995 and a Variable High Pass Filter I designed and built a few years ago.  Because of the scarcity of the original Dredge PC boards, this version is limited to 5 remaining units.

I assemble these units in my garage still, although now that garage is in Olympia WA and not Berkeley CA.  Some things that change really don't, do they.

The 2025 version can be ordered from the DredgeTone Reverb Site now!  If you want and NOS 1995 version please get in touch at jmjoseph88@gmail.com or  dredgetonepedals@gmail.com

Below are the descriptions of the DredgeMore Controls:

Gain: Sets the drive of the OD/Dist stage, controlling the amount of signal clipping.  It’s a logarithmic taper pot allowing some dynamic control of the overdrive when set at 1 o’clock or below.

TOP Switch: 

0  = No Top Boost

1kHz = Top Boost @ ~ 1kHz

2kHz = Top Boost @ ~ 2kHz

LO CUT: Sets the lower cutoff frequency of the output stage High Pass Filter.  At full Counter Clockwise the cutoff is at ~80 Hz and essentially out for a guitar. At full Clockwise, the low frequency cutoff is at ~1.6kHz, and well, that can be pretty interesting.

LEVEL: Sets the overall level of the pedal.  

POWER: Uses standard, 9V, negative tip pedal power.

This is the brand new DredgeTone Angler Bass Overdrive.  The original debuted in 1997, and has been out of production until now.  The circuitry has been  updated from the original in a few cosmetic ways.  The Tone circuit is  exactly the same as the original, and the drive section is both the same  and different.  The same in that the board layout is the same, and  different because there is the option to choose Germanium diodes instead  of Silicon.  The original used 1N914 or 1N4148 diodes.  The new version uses those or 1N34A Ge diodes.  Other differences are the addition of a  "Mix" control, allowing a variable amount of clean signal to be added  to the output stage and an internal, ultra quiet, bipolar power supply  allowing for a direct coupled signal path that does not cut out the low  frequency part of the signal.  There is no internal  battery connection  inside and all units operate at +9V  or +12V.  

The electronics for these units are hand built and tested in Olympia WA.

I have 7 original 3 knob units from 1997 with new enclosures.  If you want one, please get in touch at jmjoseph88@gmail.com or  dredgetonepedals@gmail.com 

 The DT JFP is a variable gain preamplifier pedal utilizing an ultra low  noise JFET as the amplifier element.  This is a limited run of 8-10  units, and when they sell out they are gone.  It's a one stage FET  circuit, so the output signal is inverter with respect to the input and  the linearity is dependent on the power supply voltage.  The power requirements are 12V to 18V on a standard negative tip plug.  With a 12V  power supply, the circuit is very non-linear and compresses/overdrives at most mid to high gain settings.  With an 18V power supply, the circuit is clean and linear at all gains with a normal guitar level input but can get to an overdrive state with the gain all the way up.   Experiment with different power supply voltages to see what sound you  like best.  Please do not exceed 18V!

This here pedal is the first in a limited series of stompboxes that I built to recreate some of the sounds of my younger days.  I used a Tech21 SansAmp on the floor (yeah, pre-pedal board days) for many a year during my HKP days starting in 1989.  The AmpLess circuit is based on the Tech21 SansAmp, but many of the parts have been changed to alter the tones available.  And there are many tones available from this box.  The differences start with a row of robust toggle switches instead of the mini dip switch unit.  The next big one is that I changed the design to operate on +/-8V, eliminating the need for many of the usual low end cutting blocking capacitors needed when operating on a single sided supply.  Another difference is that I ditched the usual TL072 OpAmp for a part created in the 21st century with much lower noise.  The final major difference is that I used high voltage Film capacitors for all of the signal path capacitor components because they produce tones that I like better than what most ceramic caps produce.  The original SansAmp used surface mount caps in the signal path, so the DT version will sound different.   There is no internal  battery connection inside and all units operate using standard, 9V, negative tip pedal power. 

I built 5 of these stompboxes, and only 4 will be available for sale for now.

This here pedal is the second in a limited series of stompboxes that I built to recreate some of the sounds of my younger days.  My first gig quality amp was a Sunn Beta Lead head  with a 2x12 cabinet.  I got it in 1979 and it was a rockin' great amp that I loved.  I have nothing else to add.  The BetaPre circuit is based on the Beta Lead preamp with a few extra tone switches to allow a bit more tonal flexibility and some changes make it more DredgeTone and less Sunn.  The picture is an empty enclosure that will arrive in a week or 2.  The main differences are the added frequency filter shift switches and component selection.  The switches provide 2 different midrange shifts and one treble shift.  The component selection changes include a more reliable CMOS inverter chip and newer lower noise OpAmps.  I also replaced all of the Electrolytic caps in the signal path with Film Capacitors.  You can use your guitar volume knob to go from crystal clean to way over the top crunch or fuzz.  It's crazy.

There is no internal  battery connection and all units operate using standard, 9V, negative tip pedal power. 

I built 5 of these stompboxes, and only 3 will be available for sale once the enclosures arrive.  If you are interested in the Beta Pre, please contact me at jmjoseph88@gmail.com or  dredgetonepedals@gmail.com .   Once the first run is gone, there will be a minimum 2 month wait if I end up building more.

BetaPre units will be available on the DredgeTone Reverb Site soon

 This is a one-off  of the EHX Hot Tubes clone.  The PCB is from AION FX, and the  parts and assembly are all Dredge.  My first ever Fuzz/Distortion box  when I learned guitar as a kid was the original, EH Hot Tubes.  The one  in the Chrome plated MemoryMan box and a 2 prong death cord to plug into a wall socket.  I loved the sounds that I got from that pedal and my Solid State QSC 1x12 combo amp.  Anyway, I built 2 of these recently for fun.  I'm keeping #1, and #2 sold after 1 day on my Reverb Site.  I made a mistake on the front lettering.  It should have been Hot Tübs.  I might make more, but with my own PCB layout  and a fix of the naming on the box.

Please get in touch if you think you might want one of these units at jmjoseph88@gmail.com or  dredgetonepedals@gmail.com .    

This is a one-off clone of the LoveTone Big Cheese. 

The PC board is from AION FX, but there are a few changes to the circuit and parts to make it more Dredgy.  I've never heard a Big Cheese, so I don't know if it really sounds like the original pedal, but the fuzz part of the circuit reminds me a bit of the circuit in the Foxx Tone Machine, which I absolutely love.  The BC, flat out, has a way better tone circuit (the same topology tone stack I put in my Angler pedal in 1997 but tuned for guitar and with way more flexibility) and an extremely clever way of doing the clipping by using the EB and CB junctions of an NPN transistor in the signal path.  Also, the "Cheese" setting is catastrophic sounding and yet a bit beautiful.  Kudos to the LoveTone circuit genius!    I think I love this pedal more than my attempt to put an FTM in a tiny box (yeah, I only made one of those too and it was my go to Fuzz for 20 years).  

I built 2 of these, and plan to keep #1.  #2 should end up on my Reverb site soon.  I might make a few more, but with my own layout of the PCB, and a few circuit changes to get a bit more sensitivity in the Mold setting.  

Please get in contact if you are interested in one.
