Re: My thoughts on Perpetual Burn vs. Custom 5
I thoroughly enjoyed reading this thread.
I found the Perpetual Burn a very strange pickup in my Carvin:
1. While the JB has a certain bounciness to it that makes it pretty nice for those relatively high-gain bluesy classic rock solos, the Perpetual Burn sounds more clinical, more like a Custom - which is to say it not as good for juicier pentatonic lead parts on the bridge, which you'll hear in Images, Altitudes, Blue and other Jason Becker or Cacophony tracks. One really needs to soften pick attack for those parts on the Perpetual Burn.
2. The Perpetual Burn isn't the best for those meaty sounding Steve Vai or Marty Friedman bridge melodies. I still find the Carvin M22SD (loading on another Carvin guitar) far more suitable for the applications stated for the PB on the Duncan website. It splits better, and sounds better clean, and with the volume backed off for Led Zepp and AC/DC parts, too and is less piercing in the highs, despite being in a brighter guitar - making it the most versatile bridge pickup i have.
3. Unlike the other two pups mentioned which are great at a lotta things on a single channel/tone, adjusting just the volume knob - the PB shines more on multiple-channels or patches, needing more EQ adjustment (rather than just gain levels) for different genres, due to having a flatter tone.
On the other hand, what i find better in the Perpetual Burn better than in the JB and the Carvin M22SD:
1. The tighter bass.
2. Better tone and more articulate for metal rhythm of all sorts - complex chords, slow thundering power chords, djenty-parts, speed metal two string riffs, death metal chugging, even the lo-fi sounding spectrum within black metal. Lacks the mid-range for ultra-low downtuning (fine down till drop C and D standard).
3. The best pickup i have played for arpeggios/sweeps on the bridge, whether clean or high-gain. Just the right balance of smoothness, clarity, articulation and attack. Jason Becker had such GODLIKE sweeping technique to be able to have the courage to sweep like that on the bridge on any other pickup, at lower than Jeff Loomis/Nevermore gain/compression levels.
4. The cleans sound better when the guitar is tuned lower, though this particular guitar is usually on E standard.
5. A softer pick attack yields very neck-like tones, more so than other pickups, making it great for single pup superstrats.
6. Tight and articulate even with the tone on 0, and at any turn of the volume knob.
7. Peculiar mid-range, somewhat like and unlike the JB: thin plain strings sound a gauge thicker and the wound strings sounding snappier or a gauge thinner (though retaining the chunk, tightness and attack of a thicker gauge, have the clarity of a thinner gauge at E standard) - probably inaccurate description but it's the only way i'm able to put it - shreddable tone at blues-level gain.
If a Custom 5 is like a '59 with 2x power, then i could totally imagine a Perpetual Burn being a Jazz bridge with 2x power.
