Small Fry Fizz

[Dendog]

Is it possible my Small Fry has developed a high end fizz? To test this I reset all internals to 12 oclock, all front controls to 12 oclock except Burn to 7oclock, and toggle is center. I played through a clean amp. Is this top end fizz normal?

Signal chain is, Hamer studio archtop, 2 hb's both on, into pedalboard powered by voodoo labs, only one pedal on and that's the Small Fry, and the amp is a AC15 reissue set as clean as I can get it. The voodoo lab is is set to deliver 18v to the Small Fry.

I recorded a 20 second clip to demonstrate. Unfortunately I cannot figure a way to attach the mp3 to this post. But here is a link to it:

What speaker? Reissue is a ac15c1? or other? what channel? what settings on the amp? what other pedals are plugged in?

Vox ac15cc, there is only one channel. New tubes, all JJ's. The master is up all the way, no trem or rev, bass and treble 12 oclock, volume 7oclock. As clean as it can be. The first part of the clip is w/o Small Fry, then you hear I hit the switch. I repeat this process once.

Speaker is the stock Wharfedale, but I swapped out a 2-12 Celestion V30 16 ohm cab and there was no difference.

I said "only one pedal on". I should have said there is only one pedal connected. I took everything else out of the chain to be sure. I also tried powering with 9v from the voodoo but there was no difference. The only thing I haven't tried is a 9v battery because I don't have one in the house.

The recording was made with an iphone which I held in my left hand while strumming the guitar with my right, approximately 3 feet from amp. The sound level was quite modest, probably louder than bedroom, but nowhere near loud enough to for rehearsal or gig.

I've had this for at least 4 years and this I never noticed. And in the past I've used the pedal, albeit rarely, for a sort of cleanish boost. But my normal settings are everything at 12 oclock with HB's, Burn at 2oclock with SC's.

So, the sound as it appears, is that fizz normal for the Small Fry?

Thank you for your help on this.

The prime concept of this forum is, to be a "Players Forum". To make this a "Players Forum" everyone who posts should have a basic equipment list and a sound clip on their signature, or in the "sounds of Barber" section. If we keep this a Players forum, and not just another redundant bunch of guys/gals throwing vaguely/possibly pertinent advise, we actually get to know the people we are taking advise from! Lets keep this basic rule of the forum well enforced, while this may take a little effort to get setup, the benefits of players getting and giving advise to people with similar style and sounds will offer a better online environment that gets to the core of tones without waste.

Please post in the correct section, this means use the "Nuts and bolts" section to ask how to modify your Barber pedal.

Thank you!

P.S. If it takes you a little while to get your sound-file uploaded, we understand.

Thank you, that helped. Do you hear the "fizz" with the Class 5 too? I looked at the schematic for the ac15cc.The Vox has a bright cap across the volume pot that would cause "fizz" at lower volume. Have you used the Small Fry with other amps in the past? Is the AC15cc new to your setup?

[Dendog]

I don't know if I would hear the fizz on the Class 5 because it has so little clean headroom. But I will test that.

I've been using the Vox as my primary amp for the last 4 years. I do know that many have removed a cap on that amp because they felt it had too much high end. However, with the settings I use normally (which would be both vols and both tones at approx 12 oclock) I never found it to be an issue.

On my sound clip, the first sound is w/o the SF engaged, and there is no fizz present. When you hear the click that me pressing on the switch to engage the SF and subsequently the fizz is present. Are you suggesting that the bright cap could be causing fizz which is audible only when the SF is engaged? In other words, is there an interaction between the cap in the amp and the SF? I'm not a tech person, I'm just trying to use logic to think through the possibilities.

Thanks again for you help with this.

Exactly! and indeed. The harmonics that are not present when the SF is off are no issue for the hi-fi reproduction that you get from a bright cap, but when you introduce harmonics (turn on OD), it can be a problem. Most people remove bright caps because they have a problem with OD or distortion, not because of the clean sound. Check it with a non-bright cap amp first to be sure though. I have never seen a SF get fizzy over use, your clip had such a low burn setting that it is hard to tell much more...but bright caps do exactly what you described.

I noticed that you are using the asymmetric mode with the toggle in the middle.... I do find that this is the most fizzy one...

here's an mp3 showing the differences of the three toggle modes on my setup.....

http://www.leftoverlasagne.com/geheim/BarberSmallFry.mp3

SF settings are

Level 12 o'clock
Tone 12 o'clock
Dynamics fully clockwise (whatever o'clock this is)
Burn 12 o'clock

internal settings

note shape fully ccw
bass fully cw
mid fully ccw
presence fully ccw

I also noticed that the fizzyness increases the more notes I play at the same time...
I wonder if this is the so called intermodulation distortion...
