What players and reviewers say
On the Seymour Duncan Alternative 8 (SH-15)
“In the tone chart I´ve seen the TB15 Alternative 8 wich is Alnico (tone) and seems to have the same highs that the JB has but It has more mids and lows too..”
“So I got an Alternative 8 in My SG and I am finding it to be a bit aggressive on the high end and upper mids..”
On the Seymour Duncan Custom (SH-5)
“Duncan Custom 5 or Gibson 498T (these are similar sounding/feeling pickups, and would be darker/growlier/not as smooth sounding overall).”
“When I changed to the Duncan Custom, I had to raise OD1 to about 8.5, but the sound is still clear, punchy and round.”
