| A/B
I A/B'd my Original Fender Blender against the Reissue, and the Reissue should mostly ignored.
The original Blender has massive low end boost that makes it sound like the best possible doom metal fuzz, with a pseudo-ringmod octave up that really comes through on chords and as you move up the neck. The Boost rendered any usable non-boosted settings into extremely bright and almost unusable intensity which would probably sound alright through a tube amp or overdrive that could soak up the extra gain/brightness, but for SS it's pretty harsh/awesome, depending on your opinion of such things. Does the "Blend" control work? Absolutely. And the Blender is not subtle in any way. It's takes your tone and completely "blenders" it; you can literally hear your notes garble and bubble out as they decay, it's pretty amazing.
The Reissue drops volume, lacks high-end articulation, and doesn't have the natural crunch and attack of the original. If you've never heard the original, then you might not mind it, but if you have, it's a no-pass. |
