GAMMA

collapse expand iconDescription

The GAMMA True Blue TB10G 10” guitar amp speaker is ideal for upgrading amps that deliver up to 30 watts of power at 8 ohms. Its 20 oz magnet is larger than that of most other small amp speakers, and is essential to the outstanding headroom, clarity and dynamics that the speaker delivers, along with ample low frequency response. The True Blue TB10G is equally at home in delivering aggressive high-gain distortion, transparent cleans or medium-gain distortion, and is a go-to driver for translating tones from your stomp boxes or multi-FX and modeling units.

      I bought this as a replacement speaker for a DeArmond Guitar 20 amp that had a very poor quality speaker. The GAMMA increased the tone, volume and sustain so much, without any distortion at peak volume. It can handle everything that this amp puts out. I am very pleased with my selection.

      Wow! I put this speaker in my Fender Frontman 25R and it made a huge improvement in sound. More bottom end and high headroom. For this price it's a no brainer. Great clean tones and really improves the gain channel in my opinion. Very pleased.

      Is the speaker "surround" supposed to be sticky to the touch? This is the outer lining of the paper speaker. it is often called the rubber foam or paper surround. My speaker surround came very sticky to the touch.

      It says, "Preorder". How long is the wait? My store is Villa Park.
