INTRODUCTION Congratulations! You are now the proud owner of The Percolator 2W 1x8 Combo from Zeppelin Design Labs. The Percolator has been designed for electric guitar, cigar box guitar and harmonica. Intended to be used in a variety of situations from a bedroom practice amp, to a small stage gigging amp, to a small studio amplifier, the Percolator should give you a lifetime of great tone.
USING YOUR COMBO BREAKING IN THE SPEAKER Your 1x8 Combo features a Jensen C8R speaker. We have found that these Jensen speakers are typically a bit stiff straight from the box. They tend to soften up the more you play through them, and they reach a nice bright, clear tone once they are mostly broken in.
Percolator around this tube: they are easy to find, but unusual in instrument amplifiers, creating a unique tone. When the time comes to replace the tube in your amp, we here at Zeppelin Design Labs would be happy to sell you a replacement, but you can also check the standard NOS tube dealers around the web, and even places like Ebay.
REPLACING THE SPEAKER Some people like to swap out the speaker in their cabinets from time to time, and for various reasons – usually because they destroyed the original speaker, or they obtained a special or vintage speaker and they are dying to try it out. We recommend you service your speaker from the rear, by removing the top port and loosening the machine screws from the t-nuts in the baffle board.
