A friend recently asked about EMG/Expert/Astra/Wild/Meltrope soundbox weights. Here are the approximate figures of items I have measured :


Approximate weight--------------------------Grams

EMG 4 spring--------------------------------------- 205
EMG 4 spring (long bar)--------------------------- 201
EMG 2 spring (large)------------------------------- 174
EMG 2 spring (medium)------------------- ------- 162
EMG 2 spring (small)------------------------------ 157
EMG 2 spring (early-51 mm)---------------------- 162
Expert 4 spring (large)----------------------------- 221
Expert 4 spring (small)----------------------------- 215
Expert 4 spring (early-long platform)------------ 209
Expert 2 spring-------------------------------------- 192
Astra 2 spring (with tonearm clamp)------------- 205
Astra 2 spring (no tonearm clamp)--------------- 210
Wild 4 spring (long bar)--------------------------- 204
Meltrope I & II-------------------------------------- 143
Meltrope III ----------------------------------------- 130

The attachment gives the figures in a slightly different format.

Thanks for posting. It would be very useful to also add pictures of the soundboxes. I'll love to see the Astra and Wild soundboxes. I'll also do some weighing and submit the results.

Thank you Graham for the pictures and info.
Here are my weight results so far.

Expert 4 spring (large) - 3 different weights- 218g, 221g & 227g

EMG 4 spring - 224g

EMG 2 spring (early-51 mm) - 156g

Meltrope III - 142g

I was expecting them all to vary slightly but was surprised that even the mass produced Meltrope III varied by 12g.

Another data point for posterity:
Meltrope III - 148g (includes 10g for the orthophonic isolator)

Notes: rebuilt with white tubing gaskets and the isolator is a Sitko orthophonic.
