I'm gonna guess it's not high gain Laney.
There is no need for anything hotter then Satriani / Andy Timmons on amp like that.
And if you have like Lionheart 5. PAF would be cool for that amp.
I love that amp. Cool toy.
Lionheart would be in my top 5 amps of all time.
I love that amp.
And 36th should be okey for it. If you have amp like that, there is no need for Tone Zone and this high output monsters. XD
PS.
And yeah, just wait someone with more experience to confirm this.
I'm pretty new at kinda, recommending pickups stuff. I don't want someone to spend money on something and later be dissappointed. So for everything, I kinda ask someone to confirm it.
But if you ask me, based on neck pickup needs, I would go with 36th in pair.
And based on amp, there is just no need for high gain.
But I think 36th is the darkest PAF of DiMarzio, so there is no need to get any other.
It´s not a Laney Lionheart, but a Cub 8. Very simple amp. Supposedly it´s Laney´s take on the Fender Champ. It has two inputs (Hi and Lo), and just two knobs: volume and tone. If you want drive, crank the volume knob or push it with an OD pedal; if you want cleanish sounds, roll back the volume knob in the guitar or amp.
It´s good to hear that the 36th is darker, since the amp has am 8" speaker, and it is very bright.
