Description

The Magical Mystery Box™ circuit is based on the "Brilliant" channel of the JMI-era Vox Supreme/Defiant/Conqueror solid state amps. This series of amps was introduced in 1967 and various models were used by the Beatles on the Magical Mystery Tour EP and the White Album, and also by the Rolling Stones, from the We Love You single through to Let it Bleed. An original Vox Conqueror amplifier was used for reference in the creation of the Magical Mystery Box™.

The pedal provides the clean, trebly sound of the amp, and has two switchable effects: MRB (Mid-range Resonant Boost) and Distortion. The MRB feature produces the same effect as a fixed wah (in fact, the Vox wah wah circuit was a development of the MRB effect).

The latest batch will by default be made without any LEDs on the foot switches, as were the first custom built MMBs. It looks cleaner without LEDs cluttering up the face. :)

LEDs remain an option, at an additional charge - please see pricing below.

Features are as follows:

  • True Bypass, with optional status LED
  • Foot-switchable MRB and Distortion effects, with optional status LEDs
  • High quality FR-4 glass-epoxy circuit board
  • Custom, hand wound inductor in the MRB circuit
  • Metal film resistors for low noise
  • 9V DC operation (power supply not lincluded). A 2.1mm centre-negative, standard Boss-type supply is required.

Prices

  • £ 249.00 (£ 298.80 inc. VAT) without LEDs (default option)
  • £ 269.00 (£ 322.80 inc. VAT) with status LED for each foot switch

Castledine Electronics Magical Mystery Box - Effects - Harmony Central

harmonycentral.com

The Castledine Electronics Magical Mystery Box is a delightful homage to vintage Vox amplifiers, capturing their unique tonalities with impressive authenticity. Its bright, clear sound and distinctive overdrive are standout features, making it a must-have for fans of The Beatles' era. However, the lack of built-in reverb and tremolo may disappoint some users, and its relatively high price point could be a barrier for budget-conscious musicians. While the build quality is exceptional, potential buyers should consider whether they need all the pedal's capabilities or can achieve similar sounds with more versatile options. Overall, it’s a luxurious piece for tone aficionados, but not without its limitations.
