Sounds like your pedal is busted.
Flick (EHX Staff)ModeratorThe Stereo Polyphase is a 4 stage phaser but otherwise uses very similar technology as the Bi-Phase. Both are designed by the same person.
Flick (EHX Staff)ModeratorThe Memory Boy does not have any trim pots inside to adjust modulation. All the adjustments are brought out to the surface of the unit.
For both units we have been making improvements in their calibration. We found early on that we tended to calibrate them too lean, meaning the signal out of the BBD chips was too quiet which results in quiet delay in some units and unable to runaway when Feedback is maxed.
Flick (EHX Staff)ModeratorOn the Memory Toy, there is a trim pot to adjust the modulation depth but not the modulation rate. The trim is labeled as TRIM8. There is an arrow pointing to TRIM8 with a bit of text on the PCB that says “Mod Depth.”
Turn TRIM8 clockwise to decrease the modulation depth. You’ll need a small screwdriver to do this and may want to start without power connected first. Once you have a good grasp on turning TRIM8 then you can apply power and listen to how the Mod depth changes as you turn TRIM8.
I recommend you do not touch any other trim pots unless you really know what you’re doing.
Flick (EHX Staff)ModeratorA volume pedal is a bit different from an expression pedal. Expression pedals have a TRS connector with all three terminals of the pot connected to the three terminals on the TRS connector. T = Pot Wiper, R = Toe Down Pot connection, S = Toe Up Pot connection. A volume pedal only has a TS connector, where T = Wiper and S = Toe Up Pot Connection (or ground). The input to the volume pedal is connected to the Toe Down Pot connection.
For the expression pedal input on the majority of EHX pedals, a volume pedal will not work as well as an actual expression pedal. So I recommend you get an actual expression pedal to connect to the expression pedal inputs of EHX pedals.
I believe the Boss FV50H is just a volume pedal and not an expression pedal though I could be wrong about that. If you want a very durable expression pedal (many are not that durable) try the Boss FV-500L. The FV-500H will probably also work fine but the lower impedance of the 500L is better suited for the Holy Stain and most other EHX expression pedal inputs.
Flick (EHX Staff)ModeratorRegarding control voltage on the MB’s exp. pedal input, the useable range is 0V to 5V. Putting in 0V to 10V won’t do any damage, try not to exceed this range though.
Flick (EHX Staff)ModeratorIn analog delays, it is normal for the hiss and noise to increase as the delay time increases. Most analog delays exhibit this characteristic.
Flick (EHX Staff)ModeratorIf the Memory Boy continues to pop while going in/out of bypass, after it has been powered up more than a minute then probably the capacitor needs replacement.
Flick (EHX Staff)ModeratorI believe the compressor is making its own popping sound which is then going into the delay loop of the Memory Boy. So the compressor is really its own problem. Knowing this it doesn’t change that I think a capacitor on the Memory Boy needs replacing.
Does the Memory Boy pop when BLEND is set to 100% dry?
Also I should mention it is normal for the Memory Boy to pop when going in/out of effect mode for the first 30 seconds or so after power up. While all the voltages get settled.
Flick (EHX Staff)ModeratorQuote:I recently got a Memory Boy and while playing it tonight, it started to audibly pop when I engaged the pedal. This was especially troublesome because, the Memory Boy being a delay pedal, the pop sound is repeated. The pop isn’t particularly loud. In fact I can’t even hear it with the blend all the way left. It’s the repeats that are the problem. Is this just something I’m going to have to live with? Does the switch need to be replaced? Thanks for your feedback.This pop is most likely due to a bad capacitor on the output of the delay section. It should be fixed under warranty.

It is a wonderul effect that allows you to set the pitch of your vocals (no matter what pitch you sing) with a monophonic instrument. It works really well with guitar but it won’t track chords.
The way it works is you play a note on your guitar, say an E at the 5th fret on the B string. Then sing into the mic, the output of the effect will be your voice pich shifted either up or down to the same E note you played on the guitar.
Think of it as Auto-Tune that let’s you play the notes in real-time. It’s great as a new kind of talk box effect or new style of vocoding. I see a lot of possibilities for live use, mixing the guitar and vocal together where the vocal tracks the guitar.

BRAVO, you’ve created another masterpiece!
It is a present and future classic.
Thanks!! You made our day.
We really appreciate the feedback both good and bad.
Flick (EHX Staff)ModeratorQuote::Can the delay get short enough to at least get into the bathroom verb range? Basically- can I do this with it?
The minimum delay time is 30 mS which is I think a little longer than the guitar at the beginning of that song. The max tim is 550 mS.
Flick (EHX Staff)ModeratorQuote:Thanks for all the helpful answers Flick! No rush, get your work done
Some more questions for when you have time:
Do the memory boy and memory toy self oscillate?
Does the expression pedal on the memory boy sweep the whole delay range?
Does the depth on the LFO get deep enough to do some flange sounds as well?1. Yes they both self-oscillate, or run away.
2. Yes the expression pedal on the Memory Boy can sweep through the entire range. You have to tune the DELAY knob to set the maximum delay time range of the pedal’s sweep.
3. It doesn’t do flange but that has nothing to do with how deep the modulation goes. Flange is modulation of a very short delay time. The Memory Boy’s minimum delay time is not short enough to do flange effects.Flick (EHX Staff)ModeratorI have to get some work done now, I’ll check back later.
