The product price includes a one year warranty and 30 day money back guarantee.

However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 5 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 90 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first two years
  • Claim 50% cash back on the cost of the policy after 5 years if it has not been used!
  • Warranty is transferable if the item is re-sold
  • Loan or replacement equipment will be provided if the product isn't repaired within 30 days
  • If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
  • The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount

Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

The CTM 300 is housed within an 18mm marine-grade birch ply cabinet that features heavy-duty flip-style handles and an internal fan to keep things cool. Built to last, the CTM 300 uses only the finest components to keep it sounding great night after night.

Beginning with high and low inputs, for active or passive instruments, this easy-to-use amp is simple but provides a wealth of tonal options. There's a dual gain stage which means either driven or cleaner tones can be selected using the 'mellow' push button.

The 3 band EQ consists of Bass, Middle and Treble and can be sculpted even further using the 'Deep', 'Mid-Shift' and 'Bright' push buttons. This makes it quick and easy to create your own tone. A tube driven and recovered FX loop, plus a tube driven DI out are complimentary features.

The CTM 300 has a user-adjustable bias for each power tube which can be set by engaging the bias mode of the dual function VU meter on the front panel. This VU meter also monitors overall output level.

The power section of the CTM 300 consists of 6 x KY88 output tubes, providing the huge grunt, warmth and headroom bassists crave.
