Crank it up to 11 using this 40-watt 1x10 Guitar Combo Amp with Spring Reverb from Monoprice!This guitar amp employs a 40-watt amplifier driving a 10-inch, 4-ohm speaker. It features a genuine spring-reverb, which allows you to capture the classic surf sound made famous by such artists as Dick Dale, the Beach Boys, the Ventures, and Man or Astro-man? The spring reverb is also useful for production of electronic music, lounge, or anything where you want to produce dark, dripping overtones to your sound.This amp features three adjustable EQ controls at 100 Hz, 1 kHz, and 3 kHz. The reverb is adjustable along with the gain level for the overdrive circuit. It has two line level inputs, one of which has a -6dB pad for use with instruments with active electronics. A line level output allows you to send the output to a recorder or mixing board and FX Send and Return jacks allow you to use external effects processors. The amp features headphone and external speaker outputs, both of which automatically mute the internal speaker when in use.Unlike most amps, which top out at 10, this amp has been engineered with volume controls that go to 11! This allows you to crank along at 10 for most of a show then, when you want that extra push over the cliff, you can crank it up to 11 and really send the audience into a frenzy!SpecificationsRated Power: 40 watts RMS @ 4 ohm loadFrequency Response: 60 Hz to 12 kHzTotal Harmonic Distortion: 0.5% (typical)Hum and Noise: -75dB below rated powerInput Impedance: 220 kilohmsMaximum Input Level: 0.7 VrmsMaximum Gain: 86dB (overdrive mode @ 1KHz), 44dB (normal mode @ 1KHz)Dimensions: 16.5 x 16.7 x 8.7 (420 x 425 x 220 mm)Weight: 19.8 lbs (9.0 Kg)*** 30-day easy returns.
