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.

  • Comments from customers who bought this item:

Powered by pure analogue bucket-brigade technology, the MXR Bass Chorus Deluxe provides the player with shimmering, liquid chorus and swooshing, metallic flanger effects, whilst preserving the important punch of your low end.

Flanger and X-Over Buttons

The Bass Chorus Deluxe pedal has top-mounted Flanger and X-Over buttons with LED status indicators. Use the X-Over Mode for playing chords and melodies in the upper register while keeping the low end in tune, this is done by the modulation in low frequencies being decreased at 100Hz in this mode.

Bass and Treble Controls, and Stereo Hardware Bypass Mode

Use the Bass and Treble controls to cut or boost lows and highs and use the TRS (tip-ring-sleeve) Stereo Hardwire Bypass Mode via an internal switch for a wide stereo sound. In this mode, a TRS to TS (tip-sleeve) Y-splitter cable can be used to send the effect signal to two different amplifiers, allowing the modulation to move from left to right.
