To introduce yourself to the OTS FM Modern Eagle Mod 100 , we first recommend you familiarize yourself with the OTS FM 100 by visiting its page.

The OTS FM Modern Eagle Mod 100  starts with the amazing FM 100 , and adjusts a few aspects of the amplifier to make it easier to play across volume levels, as well as add a few features that we feel really improves an already great amplifier.

Comparatively, the Modern Eagle is LESS dependent on high volume to reach the sweet spots.  We also adjusted the Preamp Boost to sound slightly fatter and less over-the-top.  Finally, we’ve offered more flexibility with a 3-way bright switch, as we felt the FM was already quite bright.

While the FM is irreplaceable for the purist, we feel that the FM Modern Eagle Mod will be a better fit for most players WITHOUT sacrificing what makes the FM so special.

As with all Ceriatone amplifiers, we’ve obsessed over component selection, and it uses our specially designed, custom transformers for superior reliability, frequency response, and feel.

Note: PPIMV mounted on Front Panel will be either mounted in place of pilot lamp (Marshall styles) or a hole will be drilled (OTS styles).
          PPIMV mounted on Rear Panel will always be in place of a Speaker Output Jack.

Ceriatone amps are Custom-built, hand made, hand-wired amps, built to order. There is meticulous attention to detail that is second to none, and no shortcuts are taken. Each amp is 100% hand built, hand wired point to point, and then is thoroughly tested and burned in before it is shipped to you. For this reason, it takes approx. 6-8 weeks for your amp to be built and shipped. Options can add 1-2 weeks to the "standard" build time.

Prices shown on 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 time the order is placed.

Note: We ONLY ship to PayPal verified addresses if paying via PayPal. No exceptions.
