    Main photo is for illustrative purposes only and advertised base pricing is for Chassis I w/o tubes. Photos may include options that are not included if you order the standard version of the amp or don't order all options available. We also may not offer all options available and/or shown in main illustrative photos. Photos are of products assembled by Ceriatone. We no longer sell kits. Black Tolex is standard on all amps unless otherwise stated in product description.

    Ceriatone amps are custom made, 100% hand-built, point-to-point hand-wired amplifiers using the highest quality components and custom wound transformers. Each amp is thoroughly tested and burned in before it is shipped to you. Even with long lead times (due to a large number of guitarists ordering Ceriatone amps and the Covid-19 pandemic), Ceriatone will take no shortcuts or change their build standards in the production of their hand-built amps. Lead times listed are approximate.

    Current lead times are listed on the main page at www.guitarampsusa.com and are approximate.

    Pricing shown on www.guitarampsusa.com includes the shipping cost to the USA only. We only ship to the USA, Canada and Mexico. Shipping to Canada, Mexico, Puerto Rico and the US Virgin Islands will have additional shipping. We'll invoice the difference in shipping and it is due at the time the order is placed. Paypal is our payment processor and you do not need a Paypal account to check out.
