The new Mile End Effects Ronald PreAmp 150 is based on the sought-after Roland Space Echo RE-150 preamp. And, as the original units are getting scarce and harder to find in good condition, this new recreation of the preamp could be perfect for player looking for that glassy sound. But without the high prices of the original.

The new Mile End Effects Ronald PreAmp 150 pedal is hand-made in Canada and uses high-quality components. It has a few tweaks to the original design which to better suit modern guitar players. Based on the original preamp design for the Roland Space Echo RE-150, this new boutique pedal aims to capture those glassy tones of the original circuit. It uses a JFET boost and has a simple control layout which consists of Instrument Volume and Output Level, plus a dB switch.

The design was taken from the original service notes of the Roland RE-150 Space Echo using the same obsolete and scarce NOS JFET transistors found in the original units. Then, a switchable JFET clean boost was added to the original circuit to drive the PreAmp 150 harder, so you can get some extra gain from these, should you need it.

Modern Day Circuit

The pedal aims to give you a super clean boost, like the original circuit, but has a modern-day build quality that should last you years. The pedal can be run between 9V and 18V DC. There’s also an internal trim pot to adjust the bias of the transistors, allowing you to tweak it to taste.

You can hear the new Mile End Effects Ronald PreAmp 150 in the video below. The pedal is available to order directly from the Mile End Effects website. Although the first batch has already sold out online.

RRP – CAD 199

    Nice pre-amp pedal. Just need someone now to make a clone of the Space Echo itself with a real tape and a better reverb than the original. Digital tape delays are ok but they never sound quite the same. Got the pre-amp, can we have the Space Echo as well?

      Al says:

      quite a few of those about nowadays, in virtual and hardware formats.
      loads of plugin emulations.
      Arturia. Audio Thing. IK Multimedia T-RackS. Cherry Audio, all do emulations.
      If you want a ‘real’ hardware version, updated re-engineered version of the ‘oruiginal’. check out the Echo Fix EF-X2 (though you can buy an refurbished Roland model for as much, or less!)
      Roland also just announced a new RE-2 pedal, based on the same, check their site for info.
