FDP Forum / Fender Amps: Vintage (before 1985) / Amp splatter

I have two older Fender amps... 1967 DUAL Showman into a 2x12 EVM12L cabinet and an original 1966 Super Reverb...all stock.

I run a Tube Driver, older TS9, Boiling Point and Blue Note pedal and a Keeley Son of Fuzz into either amp...not all pedals are on at the same time (usually) when on the B string and sliding notes around the "tone" seems to splatter or get raspy. I have tried one pedal at a time, various tone an volume settings on the amps etc. Do those particular Fender amps NOT take overdrive well, is it a pre-amp or power tube, the pedals, the speakers or is it....gasp... ME? The splatter escalates as the "gain" knobs are increased.


Thanks,

MG

If this is true, then they are both long over due for some servicing. This could be a big part of your problem. As far as these amps taking pedals well, they usually do it very well but theres always exceptions to anything. I've found out through trial and error that some pedals just do a better job than others with these amps. I think that would be the case with just about every amp out there. Certain combinations of gear have a special magic of there own.

Have you tried to overdrive the amp naturally without the help of a pedal to see what happens?

Well...by "all stock" I meant to say original as to no mods. The caps have been changed in both amps over the years, tubes of course etc. I should have been more clear as to the condition of the amps.

Thanks for the tip.

Update: This splatter ONLY occurs on the 1st string and 2nd string if I slide from A to B on either string with one or more drive pedals turned on. If I slide from Bb to B the splatter is gone.Sliding to B from anywhere other than A there is no effect. Nowhere else on the fretboard does this happen...and it occurs no matter which guitar I plug in...any thoughts on this?

Sounds like something in the amp is resonating at that specific frequency. Could be a component on the board or could be hardware.

Roadhog is spot on about the amp due for servicing.

Have the tech run a tone generator through the amp to see if that replicates the problem.

Does it exhibit the same splatter sound on other guitars? If not, could be the guitar and not the amp.

Try this:

Tune your guitar a half step flat and see if the problem goes away.

Yes...the noise occurs regardless of guitar...and it happens on both amps. The Super was in 3 years ago for caps, the DUAL Showman was in a year and a half ago...tubes and some caps.

I'm figuring that since it happens on both amps with all guitars it could be the pedal arrangement, even though it happens if I just activate one pedal at a time...maybe something in the chain is hinkey...

Well...I disconnected all pedals and tried each one individually with the guitar into the pedal and the pedal straight into the amp(s). Same splatter on both amps with any one of 3 guitars. I think I may have two particular amps that do not play well with overdrive pedals...maybe it's time to get something new!

Thanks,

Check your speakers.. sometimes they need to be tightened.. Once, I was thinking I might have blown a speaker in my Twin just to find out one of the speakers loosened up.

Also check the guitars actions, are you getting a lot of fret buzz down low?

I say all this.. cause I've experienced similar things thinking it was my pedals, just to find out it was something of mechanical in nature.

Yet It could the amp, My Twin takes to overdrive pedals funny, some better than others. I do have a J Rocket Blue Note and also hace used a TS and had no problems though. ( I switched out the TS with a J Rocket "The Dude" which seems to be made for vintage Fender's due to it interacting with my vintage amps so good!

As always with vintage amps taking the approach "less is more" seems to get the best results...

I determined that the "splatter" is directly related to the amount of "drive" setting on any and all of the pedals. A friend at the local music store stated that certain BF Fender amps have a tone stack and gain structure that do not "handle overdrive well". He pointed out a Deluxe Reverb Reissue and a HRD that he demonstrated...in the store...as taking overdrive extremely well. The only pedal he had in the store that was the same as one of mine is an Ibanez TS9.
I don't know if what he said is accurate but the HRD did sound like violins singing...just an observation. I will call a tech in Los Angeles who I trust and get his take on things.

Thanks,

MG
