Hey all, I have an issue with my GK NEO 115 8ohm/400W. The other night it started to "smoke" - the piezo gave out. I use a Peavey Cirrus thru a Markbass LMIII head. I want to upgrade the piezo replacement (not stock). Does anyone know of a decent replacement for my cab? This cab has very low mileage so I am guessing the horn may have been faulty or transient levels exceeded its limit.
