Just because your budget has been exhausted after purchasing your new guitar, that doesn't mean you should compromise on your amp. Dean Markley comes to the rescue with their newest offer, the Ultrasound AG15, packed with the award winning Dean Markley pure Ultrasound Tone at a very affordable price, the Dean Markley Ultrasound AG15 acoustic amp is the perfect starter amp for acoustic guitar players looking to amplify their instrument, especially for those playing small clubs and coffee houses, and who are looking to cart around a light but reasonably loud amplifier.


For a warm, full frequency sound, it features Dean Markley Ultrasound’s special design 8" coaxial speaker, known for its warm low and mid-frequency response as well as a coaxial tweeter for ultra-clear, sparkling high end.

The control panel is simple and easy to use, but intended to give you satisfying control over your tone, with a volume control and 4-Band EQ. For quiet playing, use the included ¼" stereo headphone jack.

Starting with the Ultimate Speaker Demo, an ever-increasing number of the GearTunes audio  clips are being tracked using the Radial JCR Reamp. The Reamp was invented by my good friend and colleague John Cuniberti who engineered/co-produced many of Joe Satriani's most infamous recordings.

For GearTunes, reamping allows me to record a track where the guitar "hears" the amp in the room, but initially only the guitar or guitar and effects signal is recorded. This allows me to spend additional time perfecting amp tones and mic placement once I have the performance I'm looking for. One of the byproducts of this process is the creation of GearTunes DI Clips which enable you to play select guitars and effects through your amp by using your mobile device or computer as a reamp device.

For GearTunes DI Clips - and Gear Tune DI Clips ONLY (always found under the DI clips tab for gear that has one), you can play our guitar and effects through your amp. Simply use an unbalanced cable that terminates with an 1/8th inch jack on one end and a 1/4 inch jack on the other. Connect the 1/8th jack to the output of your mobile device or computer and the 1/4 inch jack into the front of your amp. Start off with your amp volume at zero and your mobile device (or computer) volume all the way up to ensure you hit the front end of the amp with enough signal, and then gradually increase the volume of the clean channel on your amp until you reach a level that is not capable of causing damage to your ears or equipment. GearTunes accepts no liability for the use, abuse or misuse of these clips, and playing them into your amp is done exclusively at your own risk.

I am tremendously excited about being able to share GearTunes DI Clips with you as you journey on your quest to find right gear for the music you play! Cheers ~ Doug:)
