You’re playing a gig in your local bar. The stage is the size of a postage stamp and the drummer is shoe-horned in right behind you—he’s playing too loud—nothing new there. But hey, none of that matters because the joint is rocking, the beer is flowing, and your guitar sounds sweet; you’re in the zone. But wait! The beer really is flowing: as some dude leans across your pedal-board he spills some beer; it splashes over the rim of the glass and into the intricate thermionic workings of your prized Tube-Drive pedal! Red alert!
But he’s on you radar. With lightning-fast reactions, you reach down and unplug the DC power connector from your Tube Drive. With the power removed the pedal defaults to true bypass. You turn up the volume on your amp to compensate, and the show goes on. The beer-drenched pedal will just have to wait until later.
So what does beer do to electronic circuitry? Will it damage the pedal? Well, that depends on whether the pedal’s connected to the power or not. If it’s not unplugged immediately electrolytic corrosion occurs. The metal parts, such as component legs and circuit tracks, rapidly begin to dissolve. Not good. Not good at all. Repairs WILL be expensive. Unplugging the pedal was the right thing to do. With the power removed no electrical currents can flow and electrolysis ceases. If you’re lucky, all you’re left with is a sticky mess to clean up.
We do get the occasional pedal returned because of a spillage. Often times it’s simply a matter of dismantling the pedal to remove the circuit board for clean-up. Believe it or not, we use hot water and washing detergent to clean the circuit board. A little gentle scrubbing with a stiff-bristled paint brush deals with the dried up beer and any sticky, sugary residues. We then flush the board with hot water, then with isopropyl alcohol (IPA) and finally dry it with a hairdryer. Of course the best thing is not to get beer in there in the first place, right? But how?
Gentlemen we have a solution: I give you the Patent Applied For, anti-beer-spill widget from Effectrode, aka 20mm x 3mm Viton O-ring seal! Protect your precious all-tube effects pedal from electrolytic corrosion caused by sugary and alcoholic drinks with this innovative little device. It also prevents dust getting inside the pedal too. The 20mm diameter O-rings will fit JJ tubes and the vintage Brimar tubes, which possess a slightly narrower diameter glass envelope. I really ought to have announced this before Christmas, shouldn’t I?
Happy New Year to all you good people.
