FDP Forum / Miscellaneous and Non-Fender Topics / I had a weird issue with my pedals tonight

I replaced my Wampler Tumnus Deluxe tonight at practice with a J Rockett Melody EQ/OD. I'd seen a video by That Pedal Show where they put an EQ in front of a Keeley BD-2 and produced pseudo Dumble tones. I had the Tumnus after the BD-2 but rearranged it so the Melody was in front of it.

I was getting some great tones but started noticing an intermittent volume drop while playing. Thinking it might have a bad tube, I swapped out the amp, but had the same issue. After more experimentation, I determined the volume drop was occurring whenever I engaged the Melody along with the BD-2. The BD-2 is always on.

I put the Melody after the BD-2 and the problem went away. I've never had this issue with any other pedal combo. I can't imagine what would cause it except the BD-2 is about 15 years old. Could I have been saturating the input of the BD-2?

Sounds to me like the eq had a lower gain factor than the bd2. Were both set to unity gain beforehand? Sometimes you get pedals that won’t play nice with each other in certain orders.

They were both set just above unity with mild OD on both. The Melody's gain was slightly higher than the BD-2.

I cannot imagine you'd "load" the BD-2 to that point.

I run VERY HOT line level signals through my Boss pedals with regularity.

If it was intermittent, that would suggest either a faulty pedal somewhere, perhaps a funky cable, or an underpower situation. Can your power adaptor handle the load of all your pedals on at once? Doesn't look like you have anything hugely power hungry there.

EQ before overdrive is part of the Dumble formula. That is a weird thing you experienced.

I checked all of my connections and even replaced my guitar cable. The patches cables are fairly new Sweetwater EBS's and they've been flawless. I'll try it again to see if it's repeatable.

Curiously, I now have the EQ before the Plimsoul with no issue.

The power supply is a Truetone CS7.

It’s the magic of pedals. Or Ohm’s law. 🤔😜

How’s the new pedal? We’re waiting for your review. 😊

It's a really cool idea to combine an OD with an EQ. The OD circuit is the J Rockett Dude. It's very amp-like and not gritty. I can dial in close to my Keeley BD-2, although the BD-2 still is more open-sounding.

I'm much more happy with the new Melody than the Tumnus Deluxe it replaced. The Tumnus is a nice pedal and well-built. I just never warmed up to the midrange's voicing. Now, with the Melody, I can EQ whatever voicing I want.

I'm going to experiment today with the Melody before the Plimsoul to see if I can approach the Dumble sound. The Plimsoul has higher gain than the BD-2 but still cleans up well, so we'll see if it works.

I think I found the problem. The power connector had a loose connection. I fixed it and then intalled the EQ before the BD-2, It seems okay now.

Here's the updated board. I removed a Blue Bird Tremolo and Wampler Tumnus Deluxe and added the J Rockett Melody and Wampler Ego V2.

Cool that you found the issue. I had a similar weird volume drop issue like that a little while back when I had my OCD pedal and mini Ibanez chorus pedal on at the same time. I fixed it by adding a small JHS buffer box to the very end of my pedal board. Fixed that issue and gave me a fuller, punchier sound with no loss of top end. Cool discovery! Never tried a buffer pedal before in all my years of playing. I'm sold.

BTW - The Dude is one of my favorite dirt pedals. Killer overdriven tones!

My BD-2 is a Keeley so I believe it's no longer buffered. Come to think of it, I'm not sure if I have any buffer pedals on my board.

Leftymeister: "Come to think of it, I'm not sure of I have any buffer pedals on my board."

There's an easy way to find out.

Set all of your pedals to off/non-effecting.
Unplug the power. (Making sure to do whatever it takes to not get a huge POP through the amp.)

Do you still hear the guitar?

If not, there is a buffer in the chain somewhere.
