How to unlock the Specialist Shredder achievement in Guitar Hero Live - Definitive Guide
1) extra hero power segment
2) higher base note value
3) plus one multiplier
4) faster multiplier
Each can be upgraded three times (go to My Setup / Guitar Upgrades). At the beginning each is at 1/4. The first upgrade of a skill costs 6000 coins, the second costs 9000 coins and the final upgrade costs 15000 coins.
Just choose any of them and save up your coins.
You can start upgrading once you've reached level 9 (which should not take long, as leveling up is quite fast at first). Thanks to Flopsy86 for pointing this out.
Each song in GHTV will give you approximately 150-170 coins, so this will be a long road. But since you need to play for at least 24 hours anyway, this is not that hard.
YOu will probably need to upgrade all the skills in the course of time to get all the GHTV cheevos anyway. Or to get them faster.
@Gigatoreador The solution doesn't mention this but you have to be level 9 or above to even be able to access the upgrades.
Press the GHTV button to bring up the main menu
Go down to My GHTV
Select My Setup (Guitar + logo)
Guitar upgrades is the 3rd option on this menu, it will be locked if you're not high enough leveled to access it.
Is there a best skill to upgrade to maximise coin revenue, or is that unrelated to your score?
(Online - UNOBTAINABLE DUE TO SERVER CLOSURE)
In the GHTV store there are 4 guitar skills that you can upgrade:
1) One increases the maximum amount of hero powers that appear in each song
2) Another boosts the base score value of each note
3) The third increases the maximum multiplier that can be achieved
4) The fourth increases the rate at which the maximum multiplier is earned
Each can be upgraded a total of three times for 6,000, 9,000 then 15,000 gold coins respectively, meaning a total of 30,000 gold coins are required to fully upgrade one skill and 120,000 gold coins are needed to fully upgrade all four. Hero cash cannot be used to purchase these upgrades. Fully upgrade one of these skills to earn the trophy.
