Hi, I want to replace the pickups in my Eastwood Classic 4. http://www.eastwoodguitars.com/Bass/classic4/classic4Bass_frm.htm While I love the bass, the neck pickup has been replaced under warranty because it was just moving within its own housing. Now the bridge pickup is starting to do the same. The original pickups sound good but are just badly constructed. The build quality on the rest of the bass is actually pretty good on my copy but it just does not extend to the pickups. So, I am thinking of the following three choices for replacements: #1 TV Jones Thundre'tron http://tvjones.com/pickups/bass-pickups/thunder-tron/ #2 SGD Series 3 http://www.sgd-lutherie.com/pages/ND3-HB.html #3 SGD Series 4 http://www.sgd-lutherie.com/pages/SW4-HB.html I understand that SGD would have lead time issues but I can wait on this so it is not really a consideration for me. Any suggestions/comments would be appreciated. Also,any SGD 3 vs SGD 4 thoughts would be appreciated. Thanks in advance.
