I prefer a rack unit over pedals, I have them in my Amps fx loop. ( never have to worry about dead batteries)
As others have said, used sparingly...less is more
Rig #1 is a SWR SM-900 with an ART SGX Nitro and X-15 or X-12 foot controller.
Rig #2 is a SWR SM-500 with a Lexicon MPX G2 and MPX R1 foot controller
Rig #3 is a SWR Super Redhead with a ART SGX Nitro and the above controllers.
I do use 3 pedals on occasion: Crybaby 105Q bass Waa, Digitech Bass Whammy and Tubeworks Blue Tube.
I use Chorus the most out of all the FX, and have created presets for Flanger, Phaser, Octaver ( -12), Delay (slapback and long) , Reverb, Overdrive/Distortion, some harmony ( 4ths & 5ths) which I 've not really used yet.
The Lexicon G2 is real nice, I'd say its on the same level as a POD, I just got another one and might be swapping the ART out of Rig #2, It is discontinued and can only be found on the used market. Michael Manring was using Lexicon, and Steve Lawson uses a G2 I believe.
The ART SGX Nitro is similar to a G2 or a POD, but is also discontinued.
They made some nice gear, I believe ART was started by former MXR employees.
I have 2 ART Nightbass pre-amps/fx units as well, Stu Hamm was using them and on Chris Squire's website he has one in his rack.
ART is a good company, they still support all their old gear, offer upgrades and great service, all the times I have dealt with them.
although I have no experience with them, I've heard good things about TC Electronics and Line 6 gear.
I don't always play my Alembics, but have been using the above for many years with all my different basses, its all been reliable and I can get any sound I need/want to.
enough of my blabbing on........lol
different things work for different people, it depends on what you want to do and personal preference.
