We started our business selling guitar parts under the old name 'Diablo-Tuning' years ago on eBay. Our business has changed, but our belief in the amazingness of guitars never wavered. We sell custom noiseless tremolo springs that we make in-house, anodized titanium parts for Floyd Rose and Ibanez tremolos and saddle height screws in just about every flavor. Diablo-Tuning is now Monster Bolts, but we still have a mean guitar business.
