Here for sale is 2005 Patrick Eggle Wave Modulator Amplifier 1x12 Combo Tayden Speaker. It's in very good condition and comes as pictured. From PE: working with tube amplifier manufacturers worldwide and listening to our leading endorsees, made me realise that there was a great need for a 21st century version of the tube amplifier. Not a digital copy or simulation of the old classic sounds but a genuine new design. The most efficient amplifier in the world is the Wave Modulator or Class 'D' (not Digital but the fourth development i.e. Class A, B, C and D). This requires two amplifiers working together, one amplifies the upper half of the wave and the second the lower half. It was invented in the 1940's in England to amplify tube or valve radar waves but couldn't handle the speed of audio frequencies - until now! The company which supplies Mesa Boogie with all its power amplifier modules or MOS FETs is based four miles from my home and they are great friends as well as guitar enthusiasts. Together, we have developed a power amp wave modulator or Class 'D' guitar amplifier exclusively for Patrick Eggle. This incredibly efficient Class A/D guitar amplifier has no negative feedback, just like a Class A valve amp. It sounds exactly like a hand-wired tube boutique amp, with all the pure harmonics and responds to guitar sounds with pure clarity - no colouration or muddiness. The amplifier is rated at 125 Watts into 8 ohms, with a choice of exclusive design speakers to handle the amp efficiency. Available as a 1 x 12 combo, are made with tuned front horn ports for increased projection.
