Problem with ModTone MT-AD

Hey all,

I got curious the other day when I read an article about ModTone pedals in my Guitar Player subscription. So, I happily checked out the local dealer and made my way down to Standard Value and got myself a spanking new analog delay which costs only $120.

Anyway, it has been a great pedal, and I would say worth almost every dollar spent on it, until I encountered this problem - Firstly, the delay would squeal, non-stop. Really irritating. Can't be turned off. Stomping on the pedal, would just "mute" the sound, which actually wasn't muting. (More about this later) When you turned the effect back on, it's still squealing itself silly.

So yeah, anyway, the problem only occurs, when I strum my guitar, on my bridge pickup, or, really hard on, my neck pickup. This only occurs when the volume knob is full on my guitar. BTW, I'm using a Jackson KE-3 with Seymour Duncan TB-15 Alternative 8 in the Bridge position and Seymour Duncan SH-2n Jazz in the Neck position. Anyone else has this problem?

My theory on it is - This pedal produces the delay effect, by loops, and with each loop, the sound gets attenuated, slowly fading away. But, because of the really high output of my pickups, it sends a HUGE signal into the pedal, causing the circuit in the pedal to pickup its own loop, causing an infinite loop, or feedback. Sure, if we encounter feedback, the first thing do, is to either mute the source, or the output of the feedback. But, since the pedal is self-contained, I can only put it to "bypass" mode, by stomping on it.

This pedal apparently still runs when its in "bypass" mode.

Don't believe me? Try this simple test. Put the pedal into "bypass" and strum a few chords. The moment you stop strumming, mute the strings, then turn the effect on. It will actually play back the last few milliseconds before the effect is turned on.

So anyway, since it doesn't actually bypass the signal, there's basically no way stop the infinite feedback except to unplug the jack from the input of the pedal to turn it off. It's such a shame, that this great sounding and affordable pedal suffers from such a glitch. Then again, its AFFORDABLE. :p

Well, are there any other SOFTies out there who had experiences with this pedal and/or faced such problems? Please discuss.

Bypass doesn't mean true bypass mate.. :mrgreen:
Simply means the pedal ain't true bypass..

And what you're experiencing may be self-oscillation, something analog delays are known for?
 
Strange, never experienced the problem ur facing when I used mine. Maybe u need to adjust the settings on the delay until the squealing disappears?

Hi Kenneth, have you tried checking with Mike @ Standard Value with regard to this problem? That should always be the first step when such problems occur with a new piece of gear IMO.
 
Yup, i agree that you should go ask Mike about this problem... I'm sure he'll be most willing to help you. Really friendly fellow. :)

In any case, he'll most probably be able to help you with this cos he's pretty well-versed with pedal circuits...
 
Hey all,

Thanks for reply, either way, the problem occurs for me when the battery is weak and the "mix" knob is more than 12 o'clock when a high gain and signal passes through it. Fixed the problem when I used my adaptor.

Oh. Yeah the price is $120. I got mixed up with the Phaser.

@Godspeed64:
Hmm. I'm not too sure about self-oscillation, as I've been using digital delays before. This is my first analog delay. Anyway, regarding the pedal still running and picking up the signal even when the effect is still on, I've informed the salesperson at SV. Though he seemed quite confused about it. Mike was busy then though.

Either way, this pedal is gonna be a keeper, since I found out the problem. It's a great pedal and honestly, value-for-money. =P

Thanks guys,
Kenneth

I just bought the Dyno Drive pedal and it is killer. I got a great deal from Beyond Eleven.

The stomp switch is really sturdy and would you believe the in/out jacks are made of steel.

It is basically an OD pedal with a little gain, which is great for blues, because you can leave it on all the time. Just turn the guitar volume down and it cleans up, not that it is even that dirty.
