We had a great time at Kavarna! The Surfy Bear worked really well. The AmpFibians were awesome as was Tiger!Tiger!

All in all we had a great receptive crowd and I'm sure everyone had a large evening. It was great to see the regulars as well as Silver Surfer and his Mrs., Eddie Cannon, WoodyJ, Cindy, Toneboy Ron and Martha (in town from Nashville) and the distance award goes to Midwest Surf Guy for driving in from Cincinnati! I even got to meet Mad Scientist's mom for the first time. Now great is that?

Surfy Bears rule!

Wow, Ed!
Nice to hear that Surfy Bear behaves on stage too

Hey CD,

Dual Showman Amps.............. we don't need no (stinking) sound man.

Years back, when The X-Rays opened for the Beach Boys at the nTelos Pavilion in Portsmouth, VA, I gave the sound guy (who had run sound for us previously at Virginia Beach for the East Coast Surfing Championships) our two track DAT recorder and asked him to tie it across the stereo output buss and record our show. When I got home and played back the tape I noticed that my lead guitar was conspicuously low in the mix. I later determined it was because my amp was reaching out to where he was mixing and he didn't need to bring my guitar up (to his ears) in the FOH mix.

I had no idea the amp was that loud out that far.

Take no prisoners................

Traditional........speak softly and play through a big blonde amp. Did I mention that I still like big blonde amps?

I've tried the true bypass switch but replaced it with the wiring Björn suggested. I found the difference in volume to big to be practical. It could work if you find a way to increase the volume of the Surfy Bear. The downside of having an on/off switch like in the 6G15 is the ever present compression of the SB circuit. Maybe Björn has a suggestion?

Yes, true-bypass is difficult with the 6g15
The volume of wet signal varies a lot depending on the settings. One solution is to add a buffer stage and a volume pot to match the volume with the dry signal.

Sort of lurking for awhile on this thread but am curious, even for traditionally-based 6G15 circuits. Instead of a true-bypass, is it possible to rig something that simply changes such that Mix = 0 ? Not a big deal for me at home, but wonder if that might be workable or important for someone in a performance situation.

OK, back to passive sonar.

The foot switch Björn suggested simply shorts the input of the recovery circuit. That has effectively the same effect as the solution you proposed, and in that case the problem of the compressed guitar signal remains. I'll try to do some tests with a simple buffer stage to see if the boosted SB output could match the dry guitar signal. To be continued.

Ok, I see. It's not quite the same mechanism as in a tube-based 6G15 then - where the footswitch does what you say to the recovery circuit but the Mix control still has an effect on the tone even when that recovery path is shorted. But there is 1/2 a tube as a buffer in the dry stage so maybe you're onto the right track.

I see what you mean and you're right. I'll look into it.

Hey, great! That's the problem I've always had with the Fender Tank - now I'm really curious about that buffer idea! Good luck, Badger!

I'm not the one working out the Surfy Bear solution; that's Gillette. (Just pointing out that the actual 6G15 uses 1/2 of a tube as a buffer so that concept may help him if he wants to run down that rabbit hole.)

JObeast, the tank is supposed to mount onto the L-shaped wood strip (once I am happy with the gain control setting). The strip pushes the tank toward the bottom of the tool box to give clearance between the tank and the electronics. There's a ridge in the bottom section of the toolbox to hold the now absent tray, and the wood pushes the tank outward a bit to avoid the ridge. To make things more complicated, there are compression springs on the screws holding the tank to allow more vibration proofing. The simplest approach is to let the tank sit at the bottom of the box. You can't fit beer cans in that way but I'm not going anywhere.

I searched for toolboxes, and the big box stores only had plastic ones. Sears had metal ones but were expensive. Harbor Freight might be the smallest metal toolbox that will do the job.

Bjorn suggested reflowing input solder connections which is what I did but to no avail! Something must have burned out. Odd that it did this just after I finally attached than to the cork floor of the toolbox ($10 on cl) with Velcro for a secure tie-down. I've been hauling it to practice with the tank just sitting there loose for months with no issues. The capacity of the toolbox is perfect for all my instrument cables, power strip, small toolbox power supply and guitar straps.
But now no good signal passes into the unit. —
