Yes, it's one of the easiest combos to solo with actually. The "Sonic Blast" powerset has one of the best if not THE best damage-output-over-time of all the Defender secondaries due to all the stacking -resistance.
The Primary will work *best* in a team, but you do get self mez protection to Stun/Disorient, one other -resist power (Sonic Siphon) and considerable +Resistance buffs. Take Fitness and the Medicine pool (Aid Self), plus a Knockback protection IO or Acrobatics and you'll solo fine. You can cap your resistance to Smashing/Lethal if you take Sonic Dispersion and the Temp Invun. Epic Shield (and get darn close with the other shields!).
One other good thing about the Sonic Secondary for soloing is Siren's Song. It can totally negate the rest of a big enemy spawn while you "arrest" them one by one.
After reading Maelwys post, I checked Hero Designer and you can make quite a good sonic/sonic offender by not taking any of the ally shields, worth the try, I guess I am rolling up one as soon as servers are up again.
Sonic Dispersion + temp inv gives 70% lethal/smashing dmgres plus mez protection, interesting indeed.

I'd probably go for something like that for general PvE solo play plus occasional teaming, trading out Screech for the Nuke if it's more your cup of tea. You have an impressive range of abilities: 67% S/L Resist, 55% Energy Resist, full ranged attack chain, stackable sleep, a big melee "blapp" and a self-endurance-recovery power... all you'll really have to worry about in PvE is Rikti Bosses and Carnie Illusionists (ranged sleeps).
There's no real reason to gimp yourself for the rare occasions that you'll be teaming. Sonic is one of the best buff sets out there and it can make one heck of a difference to a bad AV-fighting PUG. Although with all that Resistance and -Resistance, I'd be surprised if you couldn't solo most of your own EBs... either through stacked sleeps, endurance drain or just good old "brute force" attacking... 
For PvP it'll be a different story... Sonics are usually seen more as Team Buff Bots than solo PvPers (rooting animations, Aim + Sonic Cage, allied resistance and mez protection/perception buffs) but there's no real reson why a Sonic couldn't at least hold their own in the arena. I've used my Sonic/Elec in PvP the odd time with some success (virtually always as a buff bot), but I know Xanthus and a few others have a PvP-built Sonic/Sonic.

Indeed, if you really wanted you could even cap the S/L res to 75% with tough but thats abit overkill 
Actually I was going to roll the sonic/sonic defender, but as I only have 1 villain, I decided to go for a sonic/sonic corruptor and then, as I already have a rad/sonic defender, looked for a change and ended up with a fire/sonic corruptor, not same dmgres base, but with Sonic Dispersion+Charged Armor+Tough I get a good 65% dmgres as per Hero Designer plus mez protection, which seems to be a toon with blaster damage, Inv scrapper resistance plus mez protection 
Anyway, to OP, seems that sonic/sonic is a very good soloing toon as per Hero Designer figures.
Hey this is excellent news!
Looks like I won't be deleteing "Battle Banshee" after all.
Thanks for the input/advice there all.
I have the psy epic on my sonic/sonic for the hold and psy resistance. Which stacks nicely with the psy resistance from impervium IO sets. Telekinesis is also good if you can get your end recovery high. You can stop quite a few from fighting back with the stun, hold and sleep.
Hi all,
Firstly, I need to make clear that I tend to be very much a solo player on all my alts, usually teaming only for GM hunts and TFs.
Now, bearing the above in mind, I recently created a Sonic/Sonic Defender based solely around a character concept rather than any huge urge to play the sets. Looking through the various powers and trying to plan ahead a bit with the build I am thinking I may HAVE to team with this toon if I want to get anywhere.
The combo seems VERY VERY team support oriented even for a Defender so I am wondering, is it possible to solo effectively with the Sonic/Sonic pairing?
