Bass Boost cMoy v2.02 FAQ

When will you have more amps for sale?

The cMoyBB is always in stock. However, I only post listings on eBay a few times each month.

While you wait for my next listing, I invite you to check out cMoyBB.com for news and product information.

Do you offer customization?

All amplifiers I sell on eBay are built identically. Gain can be customized upon request, although this is generally unnecessary.

Alternative enclosures are very rarely available. The following cannot be customized:

  • Input Jack

  • Output Jack

  • DC Jack

  • Bass Boost Toggle Switch

Will the cMoyBB work well with my [insert headphones]?

Having sold nearly 1000 cMoyBBs, I have received positive reviews from owners of every brand and most models of headphones on the market. Chances are, someone has tried my amplifier with your headphones and enjoyed it.

I personally use Sennheiser HD-280 Pros, Grado SR-60s, and Beyerdynamic DT-880s, plus a variety of earbuds. The cMoyBB sounds great with them all.

What kind of cable do I need? What do you recommend?

The cMoyBB uses standard 3.5mm (1/8") stereo input and output jacks. You will need a male-to-male 3.5mm interconnect cable (also known as a mini-to-mini cable) to connect your audio player to the amplifier.

I have no specific brand recommendations. Instead, I offer the following advice:

Choose a heavily shielded cable. Look for terms such as "shielded," "noise-rejecting," or "braided." These cables use an additional grounding wire and and/or shielding sheath to avert electromagnetic interference. Additionally, every cheap interconnect cable I have used has worn out in under a month, causing static, popping sounds, or a broken signal when the cable is wiggled. Invest in a rugged cable! Finally, shop wisely: A very fine cable can be purchased for under $30 USD. The cable pictured at right cost $25 USD. For the most part, highly priced cables offer no audible advantages (in other words, don't waste your money).

Are kits available?

I am highly supportive of the do-it-yourself audio community and have created a complete DIY section at the cMoyBB website. There, you will find a list of required components (including my custom circuit board), a quick assembly guide, and external links that should aid you in building your own, customized cMoyBB v2.02.

I do not sell DIY kits. Instead, the bare cMoyBB v2.02 printed circuit board is available so that do-it-yourselfers can select their own combination of parts and features. Offering kits would defeat the point the project.
